RFID - Software to Track People wearing RFID Tags - Prior Experience in RFID Needed - References Needed - India Only

I am not sure about all the server and language requirements. We can discuss this later. You must be in India. I would like to meet you before we start this project. I need the software to do the following: Work with multiple RFID Readers to cover an area of 400 sq. km or more. Track Location and Speed of Object onto a map that we create or get online. Google Maps and Google Earth is acceptable. Specs. of a RFID Module i am considering is: YS-900D RF power: ≤5W/37dBm; Frequency: 227~ 233MHz, Modulation: MSK Transmitting current: <1.6 A; Receiving current: <100mA; Voltage: DC 12V; Baud rate: 1200 ~ 4800bps optional; Range: 10km (BER=10-3@4800bps); Size: 96×58×18mm(without antenna port).. I do not know all the much about RFID. I am learning and researching. I will be getting a professional on the team who will understand the hardware side. If you know the hardware part too. Better, we could hire you for both and pay you more. Provide me with prior experience if any. Links and References are needed. Provide me with a rough outline of how you will achieve the goal. Language, Hardware and Calculation of Objects Location. Payment will be cash, in person. You will work on our computers and all work done will be ours, you will not be allowed a copy. Deadline will be 15 days.
