To be completely honest....you're not going to find them. You have to cut them and make them yourself.
I have yet to find one of the major coaches jacket suppliers (hartwell, paradise island, jerzees, and another I can't think of) that have taken the initiative to split them in half and I doubt they will.
You can always call Stuff4Greeks and buy one of theirs blank. But it's gonna cost you a pretty penny.
