JLCPCB 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.

It's incredible how cheap it is to get custom PCBs made at prototype scale these days, even ones with advanced features. It feels like we're living in a golden era of custom manufacturing.
