Starting a t-shirt company?

I'm a artist and i have a few good artwork designs that i want to place on t-shirts and sell. I'm just starting out with 4 or 5 different designs. I see there area few companies out there that do print screen and will print my designs on a blank t-shirt. My question is what is the best t-shirt printing company to go with? Has anyone out here opened their own t-shirt business? Then also, i presume i'm going to need to find a drop shipper or fulfillment service to mail my shirts to my customers. Any advice on this is appreciated as well. Thanks in advance.
