I really don't want to crash the party/ your enthusiasm, but:
I have been there done that with pictures and a big slide collection of my ancestors. I went about it as you did, got a quality flatbed scanner, software and started. Well, I was ready to toss it after twenty to thirty photos - And I hadn't even started on the slides.
Gave it to a local print/copy shop and had them do it, back then it was pricier than the scanner and software.
Currently, and I just checked one "local" site: 500 slides scanned can be had for 80,- (Euro) and 500 photos at 600dpi can be had for 125,- (Euro) and 500 photos scanned from a photo album for 190,- (Euro)
There's no way I'd consider doing this myself with a flatbed scanner ever again at these prices.
You say you have access to Adobe PS - does that mean you know how to use it, or do you really just have "access" to the software?
If it's the latter - I'd highly recommend going with something like Adobe Lightroom (or one of the many (free) alternatives) - because this will help you big time with sorting everything and to create collections and will make alterations/improvements to the pictures a lot easier. Big plus: Lightroom works non-destructive - means it doesn't mess with your original file, but keeps all alterations/edits you make to your pictures in a database/catalog. And then you simply export a (new) file when you need it/are done editing to give away (and of course to store for yourself - this way you end up with your original file and the edited one)
Kind regards and best of luck - whichever route you chose!
