...I want a camera that's easy to use and something I can grow with
Well, you'll need to decide: point-n-shoot, DSLR or hire someone to shoot your stuff for you.
1. There are many easy to use "point n shoot" cameras with built-in zoom lens that will work fine for your purpose. You don't need an extreme zoom range, just reasonable quality and possibly close-up ability (how close and how high magnification depends upon the size of the products you'll be photographing). There's a huge range of these types of cameras, everything from extremely simple, highly automated (i.e., "easy to use") to relatively advanced "bridge cameras" that look a little like and have some of the same controls as DSLRs (more potential for "growth").
2. There are a number of interchangeable lens DSLRs that you might use, too. The more entry-level and affordable of those have much of the same automation as point-n-shoot cameras, so can be pretty easy to use. But there's more "room to grow" with a DSLR, because you can "customize" it for various purposes with different lenses. Generally speaking, DSLRs use a larger image sensor than most point-n-shoot cameras, which makes DSLRs capable of better image quality. However, images for use online will likely be fairly small and low resolution and may not require all the capabilities of a DSLR.
Both DSLRs and more advanced bridge cameras also have highly automated and "easy to use" settings. They are designed for people "moving up" from simpler cameras that only offered automation, but also have potential to be used in more advanced ways, i.e. to "grow" with them in the future.
Although they could work too, I'm not suggesting a "mirrorless" interchangeable lens camera (MILC) simply because they tend to be more expensive and there are less lenses and accessories for them. MILC are the "great new thing" and are "hot" right now... and often manufacturers are charging premium prices for them. DSLRs, the other type of interchangeable lens cameras (ILC), still make up about 2/3 of the sales, though they are not increasing in share. MILC have been increasing their share of market. But MILC are relatively new... have really only been around for 6 or 7 years. As a result the "system" of lenses and accessories for MILC have not been extensively developed as yet. In comparison, DSLRs have been around for 20 years and are based upon film SLRs that preceded them... so there have been around 60 years of development of lenses and accessories for them. In time MILC will probably be the dominant type of ILC, but they aren't now and, because native lenses for use on them require re-design and manufacture, it will be many years until they match the versatility of a DSLR from one of the major manufacturers.
And, again, MILC of similar capability will tend to cost more than a DSLR. For example, you can buy entry-level Nikon and Canon DSLR kits with two lenses (typically an 18-55 and a 70 or 75-300) for under $500. There are some entry-level MILC under $500, too... but those only come with one lens (typically a 15-45 or 16-50). Two-lens kits are available with MILC, too (with a 55-200, 55-210, 50-230 or similar is added), but the lowest price I could find was $670 and most two-lens kits were $850, $900 or more.
3. Your third option is to not buy anything, but instead hire someone to take the photos for you... someone more expert at the work and properly equipped will most likely produce better images that, in turn, should help with sales. I have a client who is a capable photographer in her own right, but pays me to photograph her products for her website rather than spend the time trying to shoot them herself. She feels her time is better spent producing more products and on her marketing efforts. She also doesn't want to invest in the lenses, lighting gear and other accessories that are needed for quality images of her products. (She also hires a website designer for similar reasons, though she probably could learn to do that herself, too.)
Besides a camera, to photograph products well you also need lighting gear. That can be relatively simple, thanks to digital. But it still involves some additional gear and skill using it. Exactly what's needed - both in terms of camera and lens, as well as lighting gear and other accessories - depends upon the products you'll be photographing and the facilities you have to shoot it. For example, highly reflective items and transparent items can be tricky to shoot and needs special care lighting them. Many of the products I was photographing for the client I mentioned above were wrapped in cellophane or similar, so had to be photographed through that... both showing the wrapping and also showing the product within it well. That client also wanted a plain background that required me to use a seamless "stage". And there were literally hundreds of items to photograph, so I had to set up sort of an assembly line. Other challenging items I've worked with in the past included ice cream products that had to be photographed quickly, before they melted. And to get the shot of those that was wanted, I actually had to photograph them from on top of a step ladder... with a 4x5" view camera!
I'm not saying you shouldn't go ahead and pick up a camera and take the shots yourself. That might work out fine. Just be aware of the different options and decide the best course for you.
