I paid like 40€ last week for 5 smaller PCBAs, 0402s all nice and correct, jumpers, all my ICs. Don't have to worry about diode orientation or solder bridges. Just complete boards shipped to me. Easily beats my own labour rates.
The annoying part is getting the bom and component placement files correct. I use kicad since it's free, and there's solid instructions from most houses on what they need.
There's also a suspicion that JLBPCB may be encouraged to do this by the Party, to discourage other countries from maintaining an independent prototyping capability.
It's usually an options at the assembly house you use, bundled with the pick and place and soldering process.
Honestly it might just be worth doing it yourself if it's a few and you only need something like acrylic. Use a good flux off and degreaser, get the board spotless, and use something like this https://no.rs-online.com/web/c/facilities-cleaning-maintenan...
