Sir, we are a team of four member experties in php, mysql and C,C++ and C#. We think we can do your project quite simply because we have already done some projects related to this. We have made a project which moniters every activity on LAN network even with printscreens. This project should be no different than just logging information on the client-server network built in php-mysql and C#.
Thanks & Regards
