Swallows T-shirt Design

We need an experienced t-shirt designer to help us put together 15 versions of the same t-shirt for our printer. The only difference between the 15 versions is the number on the back (exact font is linked later in this post). The t-shirts will be navy and have a three-color logo on the left breast (attached 'TS' logo). On the back will be the number. It's a player uniform number for a baseball team in Japan. The linked VARSITY font ([login to view URL]) is the type of number that we want on the back. The number should be in white (no outline). Please provide us with high quality (vector) t-shirt designs that we can give to our printer. In other words, we are looking for someone who has done t-shirt designs before and can react quickly to our feedback. The attached t-shirt design (.jpg file) is a general idea of what we are trying to do, but we need something that is much larger and of much higher quality. We also need to adjust the size and placement of the front and back images. Thank you in advance for your interest in this project and your patience with our requests. Best regards, Pellegrini
