Welcome to the Forum, I'm sure you'll be greatly rewarded for your time here. I've picked up many a great tip in my short time here reading past threads.
I'd like to be able to give you some names in your area, as I scrapped the oilfield supply and irrigation industry in your neck of the woods 20 years ago. Problem is they're not good leads anymore, most are not even in business now!
Good Luck & Good Fortune in your new endeavor.
