Most of the thins said here are already on my checklist.
Regarding the categories, i'm thinking of a semi automated system, even more friendly as DreamsTime. Working on it.
I tested some stock sites in the past and i think i know where the issues are. But if you know more, i'm here to listen.
The problem with Paypal it's that i'm from Romania and as we speaking i expect an answer from them, because Romania it's not a country where paypal could be used.
The Moneybookers it's a real option, but i've heard many things about them, not all good(some accounts closed down for no reason). I want to start right this business, not with a questionable financial channel.
The minimum payout i think i will set it very low, as a respect for the starting stock photographers. 50$ in the account means a 50mm lens, and that's something for a starting photographer.
P.S. As you very very few know, Dreamstime it's partially a Romanian project
