High Voltage Power Board Design

I need a simple two-sided through-hole mounted board for Data communications over an 120V buss bar. All we need is the board pictured, copied. We need the Cad layout file so we can have boards made as the current ones are in bad condition due to having worked on them numerous times in the past 30+ years. No circuit design is required.

Requirements:
- High voltage handling (above 48V)
- Components: capacitors, resistors, diodes, transformer, 2 DIP chips, RS232 connector

Ideal Skills:
- PCB design experience
- High voltage circuit knowledge
- Proficiency in handling specified components
