Seeking recommendations for PCB fab houses

Hello! We want to make a small run (~10 boards) of a PCB board we’re using in a dissolved oxygen autochamber. I am new to the world of PCB manufacturing and working with Eagle so I’m barely familiar with the terminology, file requirements (e.g., Gerber files), etc. Thus please excuse my ignorance. I currently have a BRD and SCH file in Eagle (my colleague generated the files), and I’m pretty certain I need to make CAD gerber files for the PCB manufacturers. If anyone has had a good experience with fab houses, could you let me know who they are? which ones you’ve worked with? I’m hoping a good fab house would have excellent customer support, be willing to walk me through the file submittal requirements and process, be relatively inexpensive, and located in the US (I work for a national lab and I’ve been told DOE would likely prefer not to work with a Chinese company; no offense intended). We only need to make 10 boards for now, so I know that might make a difference to manufacturers. I’ve looked at OSH Park, and they currently have what appears to be a pretty good deal going for “Four Layer Boards” (https://docs.oshpark.com/services/), i.e., $2 per square inch, 100 square inch minimum, but it says they “Must be in multiple of 3” (which I don’t think I want, plus I’m not even sure how many layers I have?). I’ve googled video tutorials on how to make Gerber files, but I’d also appreciate any advice folks might provide since I a total newbie to Eagle and pcb manufacturing.

Thanks much!
Stephanie
