Simple User Data Entry Website

I'd like to start an HTML website for a book series idea I have, but I want users to be able to visit the website and enter their quick little antidotes to the topics I propose to them in a simple "main page" entry form. They have to click on "I agree to the terms" button before their entry can be submitted. Also, I need their mandatory contact and background information in order for the form to be submitted. I know a decent amount about Dreamweaver, Flash, HTML, and building decent looking sites, but I don't have the time to do this project right now. And I don't know how to make a decent looking back-end with data capture. I have a server for all my other websites on [login to view URL], so I just need someone to build the guts of this site and link it to a simple data spreadsheet so it's organized, by topic, to avoid a bunch of emails I have to sort through. Basics of what I need: - I want someone to make the basic site consisting of a main page (with the data entry box right on it), a "Terms of Use" and "Privacy" scroll box or 2 separate pages with that information, a FAQ's page, and an "About Us" page. There can be a simple email link on the FAQ's page for any further questions... - I want to be able to add to the categories they can write about in a drop-down menu on the entry form, so I can add more book series categories myself as I need more.
