I would download a lot of the key information and then get my Yellow Pages and look for small garages, machine shops, etc and work them

I would do a drive-by first to do a quick study

I would want to note such things as "has the shop outgrown itself?"

I would then go up, ask for the owner and brag on the amount of business, etc, gradually working in my product

See, the key is "benefitizing"–that is, how can I benefit YOU, not me

For example, as you study a shop, do you see how your product would benefit the owner?

Who can you "benefit"

Next, know inside how low you will go in price

Are you willing to take a loss?
