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.
