Hi, We can design this hardware with a production cost of $US 2-3. You have to escrow the project cost. After we complete the project only then you have to release the payment. This is just to make clear that I am not asking for any advance payment. I have a 19yrs of design experience in Hardware,microcontrollers, firmware and power electronics. Thanks, Amit
