Elgg Health social network

I'm doing my thesis and using elgg to do it. My project is a social network with 3 different types of users (Doctors, Patients, Researchers) I want a developer with a resonable price (because I'm still a student) to do this points that I need to finish. Tab Member ->Doctors should follow patients instead of being friends. I think that is already done, but I can't "get" that information in other sections that i need it. Tab Agenda -> The doctors need to have a possibility to add patients to events that they create Tab researches: This is a custom item that I made to my thesis, but I don't know how to complete all the requirements that my teacher wants -> Step 2/3: -> In filtering, when a User Doctor selects patients should appear only the patients that he are following -> Why after creating a research, when I create a new one appears the data from the previous research ->Put the social network able to receive "new trainings" that will come with their own variables to be applied in researches, and present the results throw graphics. -> Do a custom "game" in flash or java to test the previous functionality -> When clicking in a researcher, put that page operational -> Put the analisis of the results, the graphics, and the export to excel and pdf operational -> Completion (% of users that are doing the research) General: -> Turn the social network buttons functional, even on to register -> Add widgets: Forums; event calendar, latest trainings to the front page after log in Regards, Artur Vieira
