What do you look for in an online seller?

The reason that I ask is that I am looking to start selling fish online... here is some ideas: Live Rock (Fresh and Salt water) you ever try cycling a tank and say I wish someone sold live rock for a fresh water tank? I want to sell rays, but my passion is with the Plecostomus. Most of what I would plan to do would be special orders I would post my order lists for a couple of weeks and let you guys order what you want and then I would send them to my exporter... I would not sell any fish that come in unhealthy and would not work with an exporter that would not reimburse me for fish that die in quarantine, and would most definitely quarantine for a MINIMUM of two weeks NO Exceptions...
