Hi. I've just spotted this one, I wouldn't normally bid, but I'm currently running a project in Illustrator and could do this within a few hours, - quickly and cheaply.
The design doesn't look to intricate (I've worked with silk screen before), but I'd need a little info on the grade of the silkscreen (dots per inch) you were planning on using (somewhere between 80 and 200 if memory serves me right)... This would dictate the proper technique, I could create the image, anything from a 1bit halftone, all the way up to a pure vector, it will all depend on your mesh.
Anyway, I won't go on and on, I'm sure you'll have lots of proposals to read through, but if you have any question or would like to chat in more depth, pleased don't hesitate to get back in touch.
Best regards
Mark
