Agent Network Portal

We run a Network Marketing / Multi Level Marketing scheme where agents sign up under a network and earn commissions for selling our services and recruiting new agents on board their teams. We require a website/portal that allows us to manage all our agents and the commisions and from a agent perspective allows them a way of getting training and finding out about their commissions as well as helping them to sell the service and recruit more agents. Please find the document attached which is a brief specification of what is required. I am hoping that together with the chosen developer i will work closely to build this site. I will do the content but need the developer to do the portal development. I am based in the UK and i would like to work closely with the chosen develper in building a solution but also to make sure that they understand exactly what is required. The portal needs to be completely customisable from a administrators point of view and provide an agent all the tools to be able to go out and get customers. Any language of choice, but it needs to be all web based. The database needs to be developed from scratch and some integration to existing CRM systems will need to be made. All SQL Server based.
