ClickBank HTML Form Post / Instant Notification to database.

I need my back-end instant activation membership "html form post" when a new customer signs up for our service via ClickBank payment processor. We currently run a lifetime membership website, When someone enrolls in our program ClickBank processes the transaction through their own system and send customer to our [login to view URL] page, and we need to capture certain data that the customer is entering, i.e. name, email, etc. The database is ready, I have been registering customers manually in our admin panel till now. Now we need to make this full automatically. You may have to use the pre made clickbank Instant-Notification php [login to view URL] [login to view URL] [login to view URL] My budget is max $50
