What US based Dahua vendor?

[Adam5]

I work for a large company, we need to purchase via PO so AliExpress is out. We will also need to purchase from an authorized reseller for warranty purposes. My recent experience with B&H is less than great so I'm looking for options. I'm looking for a vendor that can handle me purchasing 100 cameras at a time. Dahua's website is of 0 value for finding authorized resellers.

Where do you guys suggest?

Thanks.
