If there is, it will be expensive, espceially for a silk screened tee. I had a friend that worked at a sceen printing shop and I know that there is a set up fee, then you have to pay for each screen. Now, every color you use will be on a different screen, so the less color you have, the cheaper it will be. You're probably better off buying your own silk screen mateirals and ink, and doing it yourself.
The printers that print the actual screens in screen printing arent cheap. Its a little more complex than you think. You would need the screen making hardware unless you bought pre made screens and they aint cheap. You would also need the hardware and chemicals to etch the printed screen. Do a silk screen search, silk screen printers, etc
