Painting house numbers on the curb – sales pitch is that it’s a safety benefit (fire, ambulance can find you faster), a convenience (particularly reflective numbers that help at night), even a legal requirement (in some towns). Capitalization super low. Add to your number-stencil inventory ones for locally popular sports teams, offering colors that declare team loyalty. Branch into mailboxes, mailbox posts, on-house numbers. If someone has missing or illegible numbers chances are it has been an irritant but not a priority – easier to sell something that scratches an itch. Outright artistic renditions or legible!-but-fancy fonts more practical on mailboxes. Fairly affordable capitalization to branch into outright replacement mailboxes, posts. Great earning opportunity for youngsters right in their own neighborhood.
I surprisingly get a lot of people asking to detail their car. I never intend to make a business of it, but I love doing it to my cars and people ask me to do it to theirs. All it takes is a cheap orbital buffer (mines a used craftsman) and a shop vac. I normally get easily $100 for a basic wash/wax/vac, or $200 to remove scratches and polish then wax the car.
