Project Management forum

We are interested in getting a custom web based system to be developed in quick time. The system will have functionality common to a ‘project management’ software and a web based forum. We are after expert Java/JSP/Servlet/MySql developers. We want the Job to be done in 20 days or less. The project is not very complex initially, hence am not expecting very high quotes due to limited budget ($500). However, we would like to add that if the project is impressive enough and works like a charm, future enhancements in the form functionality and scalability may definitely be expected with much better budget. A detailed specification document is attached. The design should conform to industry standards.
