Don't worry about the colors, I work in pre-press ;) I always send all files what the client needs for different products (T-shirt, flyers, promotional items, web, etc.).
IMPORTANT! This is not an offer or arrangement, I just answer to your question and informing you how I usually work. Still 3 days left from this contest :)
Will you print only in transfer or in screen print too? Would you like to see this logo without halftone?
