Where ever you go, just make sure to ask what they can do in-house.
Here is one example of an on-site lab that specializes in hand printing:

They also sell preservation materials.
I scanned a bunch of old vintage negatives myself for a film project on a cheapie Epson flatbed scnner and got really good results, so it does work, hit or miss - the rule of thumb is to scan low contrast - but ideally you should use a pro negative scanner with a dedicated slide/neg tray at a really high resolution. So using a digital lab is another option too.
