duckee,
Before you bang your head on the floor place a felt furniture protector on your forehead so as to not damage the floor (Just kidding)
Too bad you are not in Washington state. What I have been doing is offering
do-it-yourselfers in my area another option between having a pro do the job which can be expensive and doing it themselves which can be dangerous. (grin)
I go in as a coach on an hourly basis. Basically my "customer" becomes a "temporary apprentice" and I become a "mentor". The customer knows my hourly rate and decides how much or how little help they need and can control costs that way. My 30 years of experience can go a long way towards a successful result.
This arrangement works well for all concerned. I get to see my work thru the perspective of someone who has never done this before. I stress saving money, doing it the easier way, tricks of the trade and recommending materials.
I also do online consulting for people who are out of my area.
I highly recommend the Alto EZ-8 sander that is rented my Home Depot's full rental stores.

This is basically the same machine the pros use only smaller and it runs on 110V instead of the 220V that the professional sanders use. Let know if I can help you in any way.
