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.
