Where to make picture card thank you's in nyc??

Other than uploading a pictue to Shutterfly etc...where can I take a negative and have it made into a picture card. I would do a shutterfly or something like that but A) it is a negative and B) I really want to put one picture on the front of the card and a picture on the back. Sort of like the TY cards I have seen Imagine Studios do for their clients.

I guess I could scan the proof of the negatives I want to use and try to do it myself but I am afraid the quality will not be very good. I am in the city so If someone has a suggestion that would be great!!!

I'd definitely try out Duggal on 23rd street between 5th and 6th. They are a pretty well known photo lab and I'm sure they can steer you in the right direction.

ETA- Linda from Linda's Lovelies did my picture card thank you. Maybe she can help? she's a vendor on this site, and you can do everything with her via mail/phone/email so you don't have to leave the city.
