F&R Sales, highway 41 in Dalton. They charged us $4.50 for colored image on front and back, white shirt. They are heat transfered and you can also get different colors for $1 dollar more. 706-226-8564
Arrow Graphics in Maryville (982-0107) does screen printing. It's $15 to convert your artwork to the screen and shirts start about $4.50 each for one color. With 2 colors you are still under $5. I have always ordered colored shirts; white may be cheaper.emoSun
