Sorry for asking again xD

I want to start selling adopts next month, I am working on the suggested ones from the "contest". My question is: How much should I sell them for? I need to sell as close to 100 adopts by May to pay for my plane ticket to go visit my boyfriend in South Carolina during his break. So I would like to price them cheap enough to where people would buy, BUT I don't want to underpay myself too much, I know I will have to a little bit in order to sell the majority, but I don't want it to be not worth my time, it takes me a long time to do digital work, 5 hours minimum on a chibi digital piece, but the adopts will be easier somewhat, all I have to do is draw different hairstyles and color....

So the adopts will be like this - http://www.furaffinity.net/view/9975475/. But different color designs and hairs, and of course the different species and stuff. I'm popular enough to sell for $8 (FACT), so I was thinking $5 or $6. Please do not tell me to sell for more because I need these to sell and higher prices do not sell for non-popufurs. So would you buy for 5 or 6?

Thank you for taking the time to read and I appreciate all of your suggestions~
