460050 Custom Facebook Template Program 2

I need a very experience programmer that has alot of experience with website based projects also. Basically the concept is for a customer to double click a .exe file and the .exe file disappears but once they go on their facebook page there will be their custom template they asked for. (program edits the page source code of that page). That is client side, however if another customer buys from me they get a different .exe with their custom template inside and once they double click they can view their facebook template and the other users that have my program running. (maybe the program can patch through what user ID in facebook is running the program and check) More info on project , just PM me
