Help with Ubercart

Hello,

Looking for a developer who has experience with Ubercart and/or Drupal Commerce.

I am setting up a “freemium” website where a subscriber can first set up an unpaid account with one role. They can then pay for an additional role which will grant them additional benefits.

If the paid account is cancelled for any reason, I want to have the paid role removed from the account. I do not want to disturb the original role.

In addition, I am trying to set up an affiliates system where, if a paid subscriber invited another subscriber and that subscriber started a paid subscription, then the inviting subscriber would get a commission every month for the life of the subscription they brought in.

I would want the website to remember who invited who so that if and when the invitee decides to get a paid account, the subscriber who brought them there gets paid. Of course, if that invitee stops paying, the commissions need to stop as well.

My last developer was making good progress with Ubercart, but then he fell off the edge of cyberspace.

If responding, please provide links to your work.

Thanks,

Al
