Adding Refferal Partner ID to Infusionsoft Contact

Hi, I need this short script written for Infusionosft API. This is what needs to happen: 1. http post will be triggerend on Contact record (http post will be triggered in Campaign) 2. http post needs to go to a script which will assign Referal Partner to that Contact record. Referal Partner is "hardcoded" meaning, it's not changing. 3. Check if there were any orders ordered Today (the day that http post is triggered) and if they are, check if Referal Partner is same as we assigned in (2) If not, assign order to that Referal Partner. Let me know if you have any questions. Please reply with your bid price and deadline when you can do it. Thanks, Tom
