For getting already-printed photos digitized, it might be best to see if your local photo/print shop will do them, but if you're comfortable sending your stuff in the mail, I have used this Kodak Digitizing Box service (it's a different company licensed to use the Kodak name). They just send you an empty box, and you send it back filled with whatever you need scanned. Once it's done, they send you either a thumb drive or download link back with your original media. There are other similar services out there, but this is the only one I've used!
