I am interested in running a website similar to www.spreadshirt.com. It don't have to be an exact copy of the site, but the general idea must be really close. I mean, particulary the part of creating the shops by the users that allow them to sell products and the aplet to creat your design have to be really well made. It would be great if the website is easy to run.
I have seen many adds considering similar projects, so it would be great if someone had done this before and could just resell his work.
