Respected,
I have worked as a full time employee for a private company which provides Vehicle Tracking Solutions as well a Taxi Dispatch System.
Currently I am self employed, and rely by freelancing and providing maintenance to my last employee.
I would like to cater to your needs, but they are not really specific, so I cannot properly bid.
Also, I am even open to make an app before you accept the bid.
Hope we make a deal.
Kind Regards
-ManoJ
