Add high end Vacation Rentals.
The Designers, Interior Decorators, Other flooring Contractors like Tile and stone...granite counter top fabricators you already know for a nice start.
You can make great money sealing new tile and grout etc, in new construction...50 cents to a dollar a sq. ft. Ceramic tile vs. travertine. More for showers, back splashes and counter
tops etc. Also- Protecting brand new furniture and rugs for your Designer friends is great money. 3 or 4 hundred an hour.
This is money you can make without putting hours on the new truck mount.
Learn upholstery and rug cleaning. I recommend Pemberton's School when you are ready for that type of cleaning.
You already know the people who will refer you to the high end folks. You want to work for them as much as you can because they are cleaning as maintenance not as restoration.
These Customers will require minty fresh breath and lots of patience...but it will be worth it.
