I presently have oil heat in my home and have been told that fuel oil can be used to power the generator instead having to get bottled gas installed. Is this true?

I figure if I am going to do this, I’d like to power the entire household: furnace, sump pump, well pump, refrigerator, stove and lights. What is the price range for such a set up? Typically, is there a percentage paid up front and if so, how much? Can one contractor install the entire system: pad, generator, switch board, etc.? Am I better off buying the hardware and then just hire a contractor to perform the installation? If the contractor supplies the hardware, what is the typical mark-up, if any?

What is the best way to determine that the contractor is reputable and knows what they’re doing?
