JotForm is one of the best form building websites I have used. It allows you to build forms without using the complex PHP code or export and upload features of other form building services.
If you don’t require using more than 10 secure SSL forms per month, you’ll be able to use the site without upgrading.
Their form template section of the site allows you to choose from many beautiful form layouts.
It’s easy to use, their customer service is good, and best of all, it’s free (depending on your needs).
