The prices sound fine to me. Got a few questions for you to ask the bloke if you don't mind.
1. Once he's done the artwork set up does he keep it on file so that whenever we go back in the future there are no further setup costs, so that people can get t-shirts as and when they want and so that we can change colours every year?
2. Can we have both types of t-shirt (The fully embroidered or the embroidered/printed) Its only a few quid between the two but for some people that few quid could be the difference between getting a t-shirt or not?
3. Do they only do polo shirts? Some people don't like and won't wear polo shirts and would prefer round necks.
4. If they don't do round neck can we supply orange round neck t-shirts and have them do the work?
5. If the answer to number 4 is yes, how much?
6. Do they do other things as well as t-shirts (i.e. Caps, jumpers, jackets)?
Thanks
