Downline Building Club

This is our first time using Freelancer, but we own 6 Referral Marketing Companies. We would like software where our members can advertise a free downline building club before they join (replicated site) We would like the members to be able to see their downline grow and give them information so they can join our other referral marketing companies (member back office). The admin side back office will need to have the ability to upload and download lists. Admin would need to be able to mark people active or inactive. Members will have in their back office pages that show their genealogy tree, listing of people in their downline, etc, along with a benefits page and a page where they can join our marketing system. We need a 3x forced matrix. We are planning to upload approx 100,000 members from our database and need the ability to email them with their log in details so they can make an informed decision if they want to become active or not. We need a way to manually and automatically compress the matrix. We would like to find a programmer/developer who can help us redesign our more complicated software packages in the future.
