Buit a project managment tool

We want a project managment tool. The app must have 3 roles: Businesman, teamleader, teammember. We want a registration page with options (email, google, facebook) with roles, a login page (with email, google, facebook). As businesman can create users or invite them via email, can create teams , projects and tasks. At teams we must have options for new team, list of teams, edit, delete with ajax. and exports options to csv and excel. At users we want option for new, list, edit,delete,import from csv and excel with ajax. At projects we want new, list,import,export with ajax. The same at tasks. The rest of functionality that we want is like the excel the is at files of the project. As teammember user can see his project , add tasks, add the status of the project and how many time works on that (with timer). As teamleader we can see the projects of the team, the members, the tasks, add new project and new taks. We need statistics page per project, for all projects, per team members. We want to be easy at use, your proposals after a search , wireframes (for understand if you know what we want) , tutorials, guides (inside the app) , and to be multilingual in external php files.
