I've no problem whatsoever with you making it, but I would suggest you might like to try JLCPCB, who provide a free online PCB design package, and will make 5 prototype for very little money - and you could sell the other four to your friends.Im sorry Mr. Goodwin, but does it really matter what the circuit board Is for, as long as its not to make a Bomb? You kinda make me think that you are putting down my hobby.
ExpressPCB was a good option in the US, years ago. $65 for 3 boards of a fixed size with limited features doesn't compare to $5 for 10 boards 2-sided boards of up to 100mm × 100mm, with soldermask and silkscreen on top and bottom.Another option, if you live in the USA, is ExpressPCB.com
They also offer free schematic capture and board layout software.
