data entry pages and calculation for joomla

We are looking for someone who can develop a webpage for our [login to view URL] website where players can enter the results of the matches and based on the rules of the federation which give or take a certain amount of points, they can calculate their ranking for the year to come. It has to include a a nice looking graph to show the win/loss ratio, a page which will show how many points they are missing to change ranking and so on. Each value they will be entering has a value and that value needs to be summed up with other values that the player already has in order to get his future ranking. all this data has to be saved and used by the player in the future. the website is made in joomla. Looking forward to your questions and bids!
