With 12 albums it would probably be cheaper to do it yourself. That will require a scanner and some technical knowledge. A scanner will cost a couple hundred dollars (up to a couple thousand) and as with any tool, once you have one you will find all sorts of things to do with it. Get one and do some experiments until you can produce good scans, then go into production.

Once you have digital copies of your family photos, expand your repertoire. Make digital copies of important documents. Wills, insurance policies, deeds, receipts for big ticket items, anything you want a copy of in the future. Digital copies can be copied and stored much more efficiently than having stacks of paper lying around.

As far as scanners are concerned, you will want a flatbed scanner for that sort of thing. It will allow you to copy things that you can lay flat. If it's too large for the scanner you can copy it in sections. If your photos are glued into an album the flatbed is particularly useful because you don't have to extract the photos from the album, a process that can easily damage the photo.
