Forex Cash Back Rebates Website

I am considering to start a forex cash rebate system like [login to view URL] and [login to view URL] but should be with better UI. I need the basic features. Signup. trade volume tracking for members. affiliate tracking for members (i believe there are 3rd party affiliate scripts out there and i'm open to incorporating that into the system) as well as a forum and some other features which will include parsing of html files. I will discuss in more detailed in private. I will ignore any generic posts and proposals. I will require the following to be in your reply. 1.1 Links to past work with affiliate tracking 1.2 OR a brief description on which affiliate script you will implement and if you're comfortable with all the tracking involved 2. Language you plan on using. PHP or asp.NET (which and why) 3. If you're willing to work for equity in the project. *preferred. 4. If you're comfortable using AJAX to make the site slicker looking. 5. Server requirements Please be prepared to talk extensively over the PMB leading up to the selection.
