You MUST have experience with clickbank API and server side email scripts, and you must demonstrate a knowledge of what I want done in your own language before I select a bid.

I need a script created that helps me run my email coaching program. My clients pay monthly for coaching via email, but it is VERY hard to know who is a paying member and who is not. I want to have a server side script that does the following:

Checks to see if the email being sent to *my email* (or other emails if necessary) is a paying customer (via the Clickbank API)

It will need to check my click bank account, or check from a list that is compiled from each customer.

When a customer refunds or cancels they are to be removed from the list.

If the customer is a paying customer a “message or flag” should be inserted in the subject line of the email OR if it is easier it can be directed to a new email address (this might be an easier script to write).

Basically I need to be able receive an email and know whether to give that email priority or not by knowing if they are a paying customer.

This is essentially a script that catches all emails to a certain account, checks the sends to a database that is hooked up to clickbank API, and the forwards the email to a new account OR flags the email in the subject line as "Paying subscriber."

Clickbank (my merchant processor) has an API that lets you access records, and do other things, but it might be necessary to make our own database that creats users that buy a certain product number, and then use the api to remove from the database on cancel or refund. Not sure.

I need to make sure that the script does not hog server memory. I get 100's of emails if not 1000's per day and if checking each email to a database is super server heavy then I have to think of another way to do this.

My old programmer may be able to give you some input so let me know if you need some input or if this looks pretty straight forward.

Let me know what you think of this, if I have oversimplified it or whatever, and what you can quote me on it OR if you are even interested in doing it.

A couple notes:

1. I need to be able to switch the clickbank item number if necessary
2. How will this work on multiple item numbers? (discounted subscriptions)
