Automated Checkout MT4 Account Number Code Project

I have an indicator I need to sell. I have a web site with a members area and a check out pretty much set up or I should say it is being worked on today. I have the MT4 indicator coded where I have to type a person MT4 account number into the indicator before I send them the ex4. I would like to automate this process where the purchaser can type their account number into the members area of the web site and then download the ex4 from the web site members area so that the entire purchase process is automatic. I need someone to write the code into the Indicator and also the web site where it is an automated process.
