I am new to Elance and purchasing circuit design services so my terminology may not be what it should. I need a design for an inexpensive device to convert various signal inputs into a standard output. This is a small project that will be assembled and sold by myself. Target price for the unassembled components is $12 USD or less per unit. I will build a couple of prototypes based on the design using bread board to insure proper function with the various inputs before having circuit boards made.

Requirements:
PCB design
BOM

Parameters:
Input Voltage: 12~15vdc
Inputs: Signals from Hall Effect Sensors, Variable Reluctors and other automotive devices with various signals (square wave, sine wave, saw tooth, rise & fall, etc) with voltages from .5v to 100v.
Output: 12vdc square wave
Max. Frequency: 2 Khz
Must be able to be pot sealed

Connections:
12~15vdc
Gnd
Input
Output

6" Leads

I will also consider offers on the PCBs being supplied as well as the units being made complete.
