I like this idea, although I am not a graphic tee designer, so I cannot comment on its viability. I think the site look and feel could definitely be improved, though. Bootstrap is a great way to get the site started, but the site feels sparse, both in information and layout. Which printers are bidding? What shirt sizes can the bidder expect? What is the expected turnaround time? Has anyone seen a success story with the service?
The website needs a lot more content and information, and it would also be nice for customers to know who is behind the site. A sales email address and an 888 phone number seem a little impersonal when so few details are revealed about how the service works--especially since it doesn't look like users register for accounts to keep track of bids?
