Project Description:
I need a custom affiliate plugin (script) for Social Engine 3.17 integrated in user area (must be up to 5 level deep membership affiliate system).
So the user earn money when a new member sign up for a paid membership through referral URL and earn money not only from direct referrals but also from new members sign up in user downline (tier) (up to 5 level tiers).
Must be easy navigation and secure plug-in!

Detailed instruction in the attachment (word doc).

The task can be done in either way – making a new affiliate plugin OR making modifications in existing plugins such as signup, subscription, referralMod plugin, user connection or some other plug-in on your discretion (if you think that it is possible to make necessary modification to fit my needs)!!! The final result must fit my needs!
Please give an accurate time frame for completion! I will not waste your time, please do not waste mine. Escrow after I will see demo version, both user and admin section (because I have previous negative experience with some programmers). Communication and update of the progress is required.

Hope on the successful and long lasting cooperation, I have more projects coming.
