Here is an interesting project. Milling PCBs though may not get the fine pitch required for some SMD parts.

This works great for single and potentially two later boards, the problem is when scale up to 4 layer and beyond boards. For quick turn production level boards I have used https://www.allpcb.com, JLPCB takes a day or so longer than ALLPCB in my experience.

For one-off pieces with 2.54 or bigger spacing there is always the handmade old school tech - drawing the traces on copper laminate with marker pen, drilling holes yourself and etching the board in ferric chloride. There is also a good old method using photo transfers and a laser printer if you not feeling like drawing it by hand. Still need to drill the holes yourself. You can re-use ferric chloride for many boards.

What are your requirements in terms of capabilities (how many layers, tolerances, etc) and how fast you need a given board once designed?
Smaller PCB mills and other similar things tend to be more limited in terms of their capabilities. Additionally, you typically do the setup and troubleshooting (which it seems you've already had a taste of) which potentially eats into the time you're trying to save.
Depending on how price sensitive you are, I would definitely consider domestic manufacturers with rapid turnaround services and do a cost analysis vs. buying and running a solution such as the mentioned Voltera.

I've been dreaming of being able to fab PCBs at home. I still haven't found anything in my price range with the reliability desired.Great Scott did a video on the Voltera, if you haven't seen it yet. https://odysee.com/@GreatScott:a/you-can-now-print-pcbs-crea... https://www.youtube.com/watch?v=8u4izLA-SC

If you mill at home, avoid FR-4 (bad for your lungs). I think you're supposed to use FR-1. But better to just outsource it.
1. Did you try JLCPCB with DHL Shipping? Price is worth it.
2. OSH Park has "Super-Swift" option: https://docs.oshpark.com/services/super-swift/
