Do you think Google Drive (and others) are secure enough to store personal financial data like Quicken? Sometimes all you need is an email and password to get in.

You can always put extra secure documents inside password protected encrypted disk images.

Lots of forms. like registration and updating user info etc.

Lots of pages that list data using tables. Different logic for changing what gets displayed on the pages. For example, showing something based on a user being logged in or not.

Client feels that it's old technology and is worried that MS won't support it in the future.

yes, I know SQL Server, HTML, CSS, I have been working with JQuery for a couple of years now. What concerns me is my backend server language. Thanks, I'll brush up on my HTML5 as well.

Interesting... I didn't think of leveraging my ASP skills. Thanks.

I would learn PHP.
