Mr. H.I. is a supposed non-trade proffesional (DIY) asking for advice to impersonate a trade proffesional (for a fee). Paying for the info on a ride along basis or joint trade basis is apparently not worth it to him...as he has to compete on price (his words). This non-trade proffesional is extended/granted (unfortunately) a great deal of influence over events that can at a minimum affect inoccent and honest people negatively.
I see a perfectly good and rationale position for all the tradespeople opinions that have chimed in. And I see no rationale reason why any particular "one" should be the equivelant of the "high road".
The HI industry has no controlling authority. That has proven to create and enable problems, IMHO.
