problem is that businesses will not touch any design with a Disney character on it b'c of copyright laws. As an individual, it's my understanding that you can use it for your own use but cannot profit from it. So that limits your ability to get someone else to do it for you. However, you could check out zazzle.com; not sure what they do but some folks have talked about using them on this board.
another option would be to ask a friend to print it out on their printer (bring it to them on a jump drive or send it to them via email). I'd use this option.
also, look for the thread that I started awhile back on how to do transfers on shirts - wording starts with "20 steps"; thread by heartbeeps. It would walk you through it step-by-step if you decide to do it yourself.
