PHP development / Customzation

Here are complete details - Don't think it's a huge project because there is a lot of text - Read it completely and send a relevant message asking project related questions or showing past similar works you have done ============================ A fully customisable Traffic Exchange script, I want to clone the ventrino script. I have bought it ( purchased it ) and you can use that script / code for customination. if you work, I shall give you ftp to download it. I want a few items removed from it and I want a few extra features added on to it. Nothing too complicated. very important only apply if your serious about your business please. I would like to be able to work with the script designers in the future, there are other ideas i would like to add into the traffic exchange and a later date. The extra features i want added are mostly payment based, paying members, i want the script to make my life as easy as possible in regards to this feature. Being the webmaster i would like to have payments properly calculated and request delivered to me in a orderly fashion and also have the payment structure of my T.E in order both from my end as well as the members side. I want free and upgraded members to be credited whenever there direct referral upgrades. I want to have full control of this payment process and I want to be able to see and i want the member to see their commissions and where there commission came from simular to how an affiliate network is. In terms of payment when i recieve payout request from members i want to be able to see how this member made his or money for the month and there preffered method of payment. I want this area to be as easy to understand as possible. So when member request payout I can see everything who he/she reffered he/she upline. Also I want to be able to add in any type of payment solution i want"example pay pal, alert pay" In this area i just want things as easy as possible to understand. like an affiliate network. Social networking exchange added into the script an exchange where members add there social networking sites. A quick way for them to get followers friends and page views. Additional added features a a directory where members can bid with there own credits on a particular directory search word(s). So if they want "make money online" the can bid 3 credits per click for that search term. Categories can be created but I have to approve them first. In total the ventrino clone with some additional features. There are a few ventrino features I want removed or modified. like the "adclicker" turned into "the directory" and the "surf and chat" into "the social media surf" the "downline builder" wont be needed. you can view the features and download it. [login to view URL] What I already have versus what the provider will build: My website is already up just want a new script from programmers who i can work with in the future. The script must be fully customizable. Other context/requirements that providers will need to know: I like the layout of the ventrino script so a simular layout will be fine I already have the template and can give to you. budget - 500 to 750 USD time frame - 2 to 3 weeks If you have any questions, ask us Consultingpalace
