This is a simple 3-4 page website that will let users to create a tool. It will require you to be aware of 'Facebook Connect based login system' and will also need you to be aware of AJAX.
1. There is a main page that will display sections like 'Recently created' and 'Most Popular' along with a Facebook login system
2. Clicking on the log-in button will take the user to a page that will display his 'Previously created' stuff and also the ability to create a new tool..
3. The 'Create new tool' section is an AJAX based form
This is basically the outline of the website. From my past experience with Freelancer this should not cost more than $100. Please bid along with your previous work portfolio. Thanks
