Hi,
I am an expert with more than 10 years of experience in the field of embedded systems, electronics, programming and pcb layout. I have worked on several MCUs including 8051, PIC, AVRs and MSP430s.
For the last 7 years I have been actively involved in the design and development of smart meters and grid equipment. I have used GSM modem to transfer metering data to the end server over GPRS network. I would charge you US$ 1000 for the project with an estimated delivery in 45~50 days.I would develop the following
1- Schematics and PCB layout
2- Parts sourcing and PCB fabrication
3- Firmware development and debugging
4- Porting the firmware to target board and trouble shooting.
5- Shipment to your address.
If you have any question pls feel free to ask
Regards
Chaudhry
