Simple Database driven web site project

We have a web site project. The basis of the site is to create a listbuilding service with a twist. Please look at and register to see the mechanics of a free listbuilding site at [login to view URL] for an example. The site requires email verification to ensure SPAM laws are considered and accounted for. The site we require designing will create unique custom accounts for members and allow them to refer other members with reward. Each person must have a unique ID when signed up, they select their own username and password and the computer issues them with a unique reference ID. This will be used later. For each 2 people they then refer, they will obtain another unique ID which only they can ever have. Admin will have access to the entire list and will be able to mail out from the web server (so allow for integration with a mail server program or build one in!). It is more in depth than this and a full brief will be offered to those that bid. Essence of site mechanics: Membership Mailing List Referral Site to allow for rewards for it's members Database driven, sets up user defined accounts and then issues a unique ID... NOTE, when they refer someone with an affiliate ID, this will be different to the unique ID they get at the start and for referring others, this is VITAL for the system design. We will design the artwork to go on the sites main sales page and logo, the designers will build the database and the internal pages, such as log in, the page once logged in etc, we will provide images to keep consistent. Any question, please PM me. Regards Martin
