alt Hacker NewsJLCPCB is often the manufacturer of choice with DIY PCBs, and the reputation is well deserved. I recommend them as well, have never had an issue with what they've made. It's a bit pricier for a one-off board given the MOC, so it's preferable to do some sort of group buy if you can.
Slight tangent: a long time ago when I was into this hobby, Oshpark was usually the go-to instead of JLCPCB. What happened to them? Macrofab too if anyone's used them.
