I already have a domain name for this site and am looking to develop it.
I am wanting it to be a payment processor calculator website. It will contain payment processors such as PayPal, E-gold, AlertPay, Mooneybookers, and RevolutionMoneyExchange (and possibly more too). Basically for each one, I want you to be able to put in an amount that you want to receive (for example $200), and it will show the expected amount that would have to be sent to you in order for you to receive the amount you entered. There should also be a section for you to put in an amount you are going to receive and it will show the fee you will incur.
You must understand how the fees are calculated for each payment processor. I will provide you with links on the fee information if you need it, otherwise you can obtain it from each site yourself.
