I am developing a database system that enables several users to connect to a database on a server via ASP. The database system also enables users to run some stored procedures.

One function in which is required is that the user can dump a portion of the database into his or her own laptop, and work offline with the running system, when outstation. Is this possible?

I am running a php script and you can choose free and paid where you pay by paypal. I want to add an option for cheaque where the visitor will be directed to a page with instruction on where to send the cheaque i.e our address and phone numbers. How do I do this.

Where can i find instructions on doing this?
