E.P.
Last year, for Christmas, my husband and I worked on an extensive project turning 8 mm roles of old family films, organized and put them on DVD's, all with the help of a place right in New Lenox, IL. I had checked around, their prices were decent and Kevin was very helpful throughout the whole project. They can attach background music or you can add your own music, if some of your tapes don't have sound (since yours is newer - you probably have sound.)

They are right in the Cherry Hill strip mall, west of Gougar, off of Rt. 30.
Just an FYI... If you want to do it yourself, and know someone with a Mac or I-Mac, there are accessories that you can purchase to do this yourself. Just go to the Mac store in Orland Mall and talk to one of their Geniuses (no I'm not being sarcastic - that's what they call themselves. They are incredibly helpful.) It is very time consuming, though. We did not want to chance it, especially since many of the films were at least 50+ years old.
Good luck.
