A photographers print shop?

Hey all. Was curious to know if everyone on here that does printing, prints and sells their own photo's? Seems like everyone on here is a photographer as well and prints to sell their own work. I'm trying to come up with as many options as possible to print for photographers in my area. I'm in deep south Texas so no one else around here seems to be catering to photographers other than big box stores. I'm focusing on mostly canvas right now but want to start venturing out into metallic and luster photo papers. There's just so many different papers I can't seem to figure out which ones to invest in and how to sell them? Just curious as to what everyone else as far as printing is doing business wise?
