Hello Reno, I'd add ewaste to the equation if you can find it.
You have 2 buyers (at least) within a big stones throw from you.
I'd be bugging them almost every day if I lived that close.
Every time I go to a buyer I learn a little something more about grading boards.
Don't stop what your already doing, maybe just add ewaste to what your doing.
Like everything else, it's not going to happen overnite. Hand a business card to anyone and everyone you see/meet.
You might try our advanced search feature up in the upper right. I know it's been talked about a few times.
