Wheel Speed Sensor Project

I am putting a new Hemi into a 34 Plymouth, and because of the electronics, I need to build a cct to deliver input to a control module, and also a couple of the gauges. The primary voltage source would be 12 volts supplied by the car.
I am looking for someone that might be interested in a small project to build this for me.
Following is a brief summary of what I need, I have a more detailed description of the requirement that I can send to interested parties.
Thanks, Gord
A. Receive a 12 Volt pulse from a sensor, and substitute the pulse with a current square wave of 7 to 14 milliamp pulses on top of the 12 volt supply (default would be 11 output pulses for each input pulse). This would be done in a linear fashion as subsequent pulses were received. As the input pulse speeds up the output pulses would accommodate this by becoming shorter in duration to map to the linear requirement.
Being able to program the number of output pulses per input pulse would be a requirement.
·
B. Use the same 12 volt pulse provided by the remote sensor, multiply the pulse 6 times and provide it as a separate output for the Speedometer.
·
C. Using a different 12 volt pulse from a signal pickup, multiply the pulse 8 times and providing it as another output signal for the Tachometer..
·
SUMMARY
If all applications are undertaken, this would require a circuit with 2 inputs and 3 outputs that could be programmed to vary the outputs.
