I am a full time Policeman in a growing suburb of Memphis, TN. I have been interested in doing pressure washing on the side for a good amount of time but I just haven't acted on it yet. I have been researching some issues such as equipment, insurance, chemicals, etc. Seems to be a whole lot of "experts" on these subjects. Luckily, I ran across this board so people with REAL experience can give me legitimate advice. I know lots of commercial business owners, homeowners, builders, etc. and I feel like I could start this side job and be successful immediately. I don't pretend to know the "ins & outs" of the trade and that is why I am here. If possible, could you provide input on the following topics: Business license/insurance, quality equipment (psi, gpm, engine types, cleaners), different types of services offered (siding, brick/concrete, deck/fence). In general, the pros & cons along with the difficulties encountered with those services. Thanks in advance, Mike Moore.
