Well, after testing out various companies, we decided that Printfection had the best product.
Take a look at the online store.

Post below what you are interested in, and we will see about putting in a single bulk buy for everything. Of course, your more than welcome to order yourself from the store. There is a wide variety of stuff. Any clothing that is displayed as black, actually has many other colors to choose from.
I can make add additional styles easily, so if you want something custom about the placement of the logo, or something on the back, etc. Let me know, and I will see what I can do to add it.
