I need Help also writing a supplier Qualification protocol also would like to know what qualifications are needed by FDA for Herbs

Can be more specific on the testing? Have you tried to speak with Eurofins? 

It sounds like you're in the business of dietary supplements. If that's true, make sure to read through 21 CFR Part 111. These are the GMP standards for dietary supplements in the US. Eurofins is indeed a pretty widespread lab company that may have labs in your area. For more affordable options I would look into smaller local labs, so long as you do your homework and vet them properly. In either case, if you're doing 100% of your testing through a third party lab you may be able to negotiate better pricing due to your testing volume.

I would look into ones like Eurofins, Alkemist Labs, Romer Labs, and Flora Research Labs, depending on what you want to test for.
