Hi sir ,
I reviewed the site you send us as demo and i've done something similar not too long ago.
I can create a copy of that website and add some new features.
Please check your PM.
Over 15 years experience developing carrier class telecom and networking applications as well as extensive web development. I just implemented a geolocation feature this afternoon on another project. Implementing additional features per your specifications should not be a problem. Please see PM for more questions.
