More pictures of your superb body
Just a few ideas, not sure if they would work....
Maybe a deals section
Quick order page
A deposit system, so maybe people could set aside a certain amount for designs and pre-pay, not sure if that would work or if people would trust it.
Pre-made toons and general non-exclusive stuff like blog themes etc. you can buy, download and start using straight away.
If I think of anything else will post them here.
