Online Art Gallery for Art-A-Holics

I have have decided to start construction of the online art gallery. I think I will probably have to charge a small amount per piece entered at the start. I really did not what to do that if you have problems come up with the money let me know we can work something out I don't want to anyone to miss this opportunity. I am going to be doing are store though pay pal to start with its the cheapest way to do it. If we start getting mote business I will switch it to more of a formal store. I have not deiced how much to charge yet my first thought was like 20 buck per 10 pieces that 2 buck per art piece let me know what you guys think. I really wish I could do it for free I just would not be able to afford it.
