Adopts World?

Okay so I changed my adopts to free for my very first batch so it's first come first serve on those. But if it's not too much of a bother I would love some advise from the people who have sold adopts before and what exactly to do for cost and what not.

Also I was wondering what would you all think of my making a world where people can let others know about adopts? Like if they were doing adopts or someone on another website was doing adopts that they think others might like a chance to possibly buy one of the adopts, they could post it up on the world and help spread the word What do you all think?
