This software is called case management system (for accident claims). I have developed it from start, I need to add some new features in it (very easy to add) but due to time constraints I am outsourcing it. I can guide you through all the requirement even point out the section of code that needs to be changed.
I have specification document which specifies every requirement. Code is checked into online cvs server so I will give you username and password and you can downlaod the code from there. I will also provide you database once we agree on work.
For an experienced C#developer this should not be more than 2-4 days work
See the attached file for detailed requirements
