If you have some volume, consider Small Batch Assembly: https://www.smallbatchassembly.com/
They are not as cheap as the Chinese suppliers, but you can provide your own components, and it is run by a very helpful gentleman in the Washington DC area. I got the bare boards from OshPark and you can order your components from distributors and send them directly to Small Batch. I preferred using my own parts from known sources, but they have a stock of components also.
