What do you show your seller?

I keep receipts (weight tickets) and make sure everything I'm involved with has a legitimate "paper trail". For me we even record what dumpster, dumpster location, brief description of dumpster contents, generated on site or illegally dumped (suspect). When selling e-waste we look for R-2 and California E-steward certified (if sold locally). As a business you are only as good as the people you employ, your own personal standards of conduct, customer goodwill, and you reputation is everything. Your best advertising are your existing customers and those you associate with.

Mechanic, you are right. My value in this deal is sorting and shipping for less than his previous refiner. I am not buying the boards. My original post was to ask what you would provide a company? An R2, itemized weights by board grade. I guess it just boils down to if he likes me or not.
