Isolated Pulse Circuit

Need to design, plus bill of materials, design/fabrication/ 3D files for a pulse input receiver circuit with the following specs:

1- The input is a square wave which translates to ON/OFF or 1/0

2- input pulse frequency up 20 KHz

3- Input amplitude from 2.5v to 24v square wave

4- Output 5v or 3.3v via a switch

5- Adjustable threshold for level 1 on the output side based on input voltage amplitude from 2.5 - 15 v

6- Terminal blocks are needed for input and output signals

Need a lump sum bid and per hour rate for any additional modifications.
