Are the tee shirt transfers you see in the t-shops on the board walk printed localy

When I started my pool company, (being cheep)we silk screened our own ts and hats.They were ok but not great.Then along came Cannon tee shirt transfer paper 4 ink jet printers.They look good and last a season or two.Can only print dark logos on light shirts though.They do make a new paper to print on dark shirts but it hard to use and costly. :( I would like to find a company where I could buy a quanity of my design logos printed with the heat transferable ink.Ive looked here in PA with no success.Any thoughts
