First you choose your online store. Then find out what they'll print (formats etc) how much they cost, delivery method/time, in fact, try and obtain as much information as possible. They will require your uploads in a certain format.
I'd suggest you join some forums and find out which sites give best value for money and quality of printing. Folks on this forum will, no doubt, have some experience of online printing so will be able to recommend places you could try. Primarily, good research, although it takes time, can save you lots of stress and, of course, $$$$$
