I am retired and have the opportunity to start a small business. I need to have access to PayPal and the use of credit cards for my customers. A friend of mine uses Zenfolio and says his customers buy his photos with CC and PayPal. In addition, Mpix and Zenfolio have a working agreement where the photo can be sent directly from the Zenfolio web to Mpix for printing. I like smugmug, and the support to build my photo web page has been excellent. I just wish they offered this option like Zenfolio.
