Development of an outsourcing website like freelancer.com

There are few developers already working on this project since the application will include more features those are not present in freelancer.com. workers need to develop few modules from the freelancer.com. I am attaching a doc file which will describe the modules in details. there is another module called "My Ads". See the following urls to get a clear idea about what needs to be done for this module.
