Mql4 and DLL programming

hello i have a finished EA that i dont wont to give my clients..I need a special copy tool.

This copy tool works on a database on a linux Server(mini Webpage) .On the Database of my server i become the signals from my EA and i can manage my clients with the accunt number.

So i need a EA that send my signals from my account to the webpage...(also when change SL,TP )

Then i need a client EA with DLL coding that recieved the signals from the Webpage...(all the important information are coded in the DLL (client login to the webpage)

Only that clients become my signals when i have enter the account number on the Database.

I can cancel clients in my database and i can add new clients...also i need expiried date.
