If you're open to something entirely a new, you can take a look at a content management system like Drupal or Wordpress where you can accomplish something like this as well.
Lastly, if you're looking for developers to help you implement this, I suggest putting your project out for a bid on one of those freelance websites like freelancer.com. You could also look locally in your city on LinkedIn or Twitter for developers in your area. It often helps to have the ability to sit down face to face.
I sell legal forms on my website and instead of just handing out a download of the file I want to make it more like legalzoom.com where you input your information on the website. What program/code/installation would be the best to accomplish this and if there any developers out there I would be willing to work with.
