Hi there:

I did take a look at those files, I should be able to make pcb boards if
I could just find which pcb system has been used for this board design.

I have the skills and equipment, but not all the time I need.

If I get this pcb onto positive film I could copy as many boards as you
would like and the boards would not be expensive.

I also could guide you through the process.
