Create join page to collect membership information such as name, address, etc. and including membership options along with credit card information. Eight levels of membership with only one having a set specified amount and the remaining 7 levels would have the value input, which is the amount that would be billed to their credit card.
There will be a submission page and results page for the client to view via the web with the options of deleting each submission in full or just deleting the credit card information.
I have specified ASP and MS Access, but am open to MySQL and other suggestions for setting this up.
This will all reside in a secure section of the site.
