getafreelancer clone

I would like to have a getafreelancer clone. Selling and buying structure remains the same, but the sites layout will be very different, nothing difficult, I will keep the details for those who are willing to work on the project. I do want to make improvements on this new getafreelancer clone and for that I also have a few idea's. Current needs... - a secure online payment function. - a unique and proffesional logo in given colours. - I would need a little graphic design. - a control panel to track incomming and outgoing transactions, that will also allow me to block or exclude members if needed. - I need a automated notification system to inform people about their balances. - The site needs SEO from the start. - I would require traffic and prefferably selling or buying members. - There would be an award system... a prize will be given away for every x number of transactions... for example the finacial transaction no 500 would get a digital camera and so on. I need automated tracking for this and transaction valued less then 50USD would not be able to compete for the prize. If possible I would like a function that allows all prizes on the site to be converted from USD to EURO maximum two, prefferably a single click. Those who bid should understand that they will only be payed when the site generates a profit. We are willing to give a generous commision on all transactions for the first year. This means that the more popular the site becomes, the more money you would earn. Suggestions of all kind are welcome. Examples are welcome.
