Recommended lab to test mushrooms for heavy metals?

Hey folks,
I decided against growing cordyceps on my own based on your answers here in the forum.
I wonder how much I can trust the materials I ordered and would be interested if you can recommend labs that test for heavy metals like cadmium, arsen, plumbum and mercury as well as other toxic residues, e.g. while drying the product.
Any hints for professional, cheap and nice laboratories?

I read about wild cordyceps being stuffed with lead to bump up the weight but why would cultivated cordyceps contain heavy metals?

There can be different sources, one is from growing medium that was not handled properly. Others are contaminations from the outer environment.
I read a lot about supplements in the last weeks and I was really shocked how many scary things can make it into industrial produced food.
Example: Some products contain unhealthy amounts of raw-oil which was brought in from the drying machines.

Another reason for me to find a good lab: I can let them test the amount of cordycepin contained. And they can test other mushroom powders i consume, like reishi, for unwanted toxins.
In case of starting to grow reishi or cordyceps myself i can test my mycelium, i remember one case here in the forum where the mycelium delivered was the wrong one (a toxin producing one). As cordyceps has no fruits and it seems to happen that you get a wrong culture I would test my mycelium before eating.

I would be curious about testing mushrooms grown in substrates from crops with high pesticide use. Locally I can get cottonseed hulls from the ADM oilseed plant for super cheap, but straw is nearly impossible to find here.

Will they sell in Less than truckload (20-25ton) quantity? That's an issue I ran into...
