I think when you run ALL the numbers you are going to find that 1) "the Boss'" price is about the same as (or more than) iDeal's or 2) you are working for $0.50/hour.
$4/yard for carpet sounds pretty good -- until you add in demo and removal of the old carpet and pad, cleaning the underlaying surface, fixing tac-strips, pick-up and delivery of the new carpet and pad, price of the new pad, installation & clean-up costs, make-ready repairs, and warranty.
I don't know about you, but I bill my time at $100/hour. Why would I want to deal with all the above when I can call Nate Gotthardt at iDeal Floors once and have him send me a bill while I spend my time on "highest and best use" (finding/doing profitable deals)?
My great-grand-father used to counsel me not to be "penny-wise and pound-foolish."
Just a thought.
