I would like to hire a Manager

I want to develop real estate management project. It manages all day to day activity in real estate group or company. There should be login of every one to track the progress of developing project and employee performance. If we gave project to other contractor for development so this can be track from this. If we Purchase any land or launch new project then every director or shareholder must approve that Purchase. Director dashboard should be different for different director. Most important thing black money should be manage so that one finds it directly and that must be encrypted.
