I work in construction and have a not-quite novel idea but novel hardware design and implementation. I am trying to design a prototype PCB to get a test build going but I'm struggling to figure out how to design a PCB. Tried using a AI service to do the heavy lifting but still running into challenges. What steps can I take to get this off the ground while maintaining IP security?

I also don't have alot of money to throw around so the more I can do or the cheaper I can do the better.
