132750 freeipod script

I'm looking for a freeipod script with some modifications. Details: Must be able to change the number/type of offers they need to complete to be eligible for the free gift. Gift(s) can be set to many or just 1. If there are many gifts they will have a choice to choose from. The number of people they refer to get this gift can be set. I also need a second level of referral system. Eg: To get the gift, he must refer 10 people, and the 10 person he referred must also refer 10 people etc. All these numbers must be editable. Also for the account sign up form, must have basic validation for email, id number, phone number etc. Checks for duplicate email, id number must be available to prevent duplicate sign-ups. The script also must include a mass email option.
