Designing a skin for iTunes

I have been an apple fan for a long time and I think I have the new iTunes design done on illustrator but I don’t know how to actually mount it to iTunes. Any ideas? I also want to offer my services as a designer, but don’t know where, any recommended sites?

There are many freelance sites you can try - Elance,myTino, Guru (they are quite expensive) RAC, GAF, SL (lower fees)...
The competition there may be quite hard sometimes.

crazy stuff, its something to do with the actual program right, you gota check in the programs source and stuff. thats crazy stuff if you pull it off it would be great
