Power meter design schematic and programming

Please read the project description and do not bid if you don't have the appropriate skills. Thankyou

I need somebody that can work with common microcontrollers eg atmel, arduino or NXP ect. The project will consist of a current sensing bi-directional hall effect sensor ACS758ECB-200B, a voltage divider circuit to measure input voltage, a standard 4 x 20 lcd and a suitable microcontroller to tie it all together. Depending on the microcontroller used an external ADC may be needed to maintain accuracy. 10 bit should be enough. I will need the bidder to provide me with a simple schematic so that i can do the PCB design. The bidder will also need to program the device to show the following.

Positive and negative current as the sensor is bi-directional

Input voltage

Power in watts/ KW

Watt hours / KW hours

Amp hours / K amp hours

Volts Peak

Amps Peak

I will design screen shots when the project is awarded to show how information is displayed on the screen and to what decimal places.

I would also like to have an external interrupt trigger the device to save its currently displayed data once the microcontrollers supply drops below a predetermined amount. The device will then use this information upon startup.

The project and code will also need to be confidential and not released afterwards. I will need an NDA signed.

Thankyou for your bids.
