We just had a great experience working with US TECH (
https://ustech-lab.com).
The price was reasonable (for what it is), the main contact was great, they were very fast and super flexible with our delays.
I know they offer CE, but we just went for FCC on unintentional emitters. It wasn't nearly as challenging as we thought it would be.
Expect to pay something around $2,500 to $5,000 depending on how labor intensive your tests are, or become.
