Welcome aboard Perry!
Just a hint...if you work with a lot of money, like in a store, grab a handful of cash at the end of your shift, photocopy the serial number side, and of course, return the money to your deposit or float. If you stack the bills just right on the photocopier,you should be able to get about 20 bills per page! Then enter them in the program, with the source, when you get home!
