If you want to shoot professionally, you'll need professional quality gear. The a77 is rather old and "superzooms" like you're using scream "amateur". Most pros would only use that type of lens as a paperweight, if they owned one at all. The Sony a77 is an SLR that uses A-mount lenses. The entire A-mount system has been discontinued. Sony now only produces e-mount mirrorless cameras and lenses.
I assume you're referring to the Sony a7II with the 28-70mm kit lens, which are selling for around $1600 right now. That camera is fine and uses the current e-mount, but that kit lens is a cheaper one with a variable aperture (f/3.5-5.6). You will want an f/2.8 lens for photojournalism!
Sony a7II (24MP)... body only is selling for $1400 new. I see it can be gotten used for around $1000.
Sony FE 24-70mm f/2.8 GM II... sells for $2300 (not yet often found used).
Sony FE 24-70mm f/2.8 GM (first version)... sells for $2000 new ($1400-$1600 used).
Sigma 24-70mm f/2.8 DG DN "Art"... costs $1100. You might be able to find it used for a little less.
Rokinon/Samyang 24-70mm f/2.8 AF... sells for $800-$900.
The other lens you will need is...
Sony FE 70-200mm f/2.8 GM OSS II... $2800 (new version, not yet avail. used)
Sony FE 70-200mm f/2.8 GM OSS... $2000 (used around $1600-$1700).
I do not have personal experience with any of these lenses and can't make recommendations. I suggest very you thoroughly research any of them before you buy.
The Sony a7II is now two generations old... there are a7III and a7IV that have superseded it, each with various improvements over the earlier model. Again, this is something you need to research very carefully before buying. Will the a7II be appropriate for your planned uses? For example, the later models have a much faster continuous frame rate, which may be important for sports photography but less critical for some other purposes. The newer models also reportedly have higher usable ISO so can be expected to handle low light situations better.
If you do a search you'll find a number of places online that compare the Sony a7 versions with each other and can compare any of them to your current camera.
You also might want to search online for detailed info comparing a-mount (your camera) versus e-mount (all the a7 models).
