I just got asked this same question from a designer that I work with... He mentioned that he's seeing a trend in a lot of clothing lines today out of the UK that are doing this and charging a decent amount for their prints (as it does take some time to develop this..
Maybe research some T-shirt templates on line.. link up with a costume designer at a local theater and see if maybe you can come up with an agreement on the clothing line... Order a huge screened frame, figure out your print head, and print a giant sheet and have it sewn together and see what you can come up with.. its going to be expensive no mater what steps you can figure out on how to skip, but thats why people will have to understand it costs more for them to purchase..
lemme know if this helps or If I'm being over- optimistic
lol.
