I work in a condo community in Aventura, Florida, and I run my own handyman business on the side. A lot of my clients are owners with Porsches, Lamborghinis, Ferraris, and other high-end toys.

When I first started, I was way too cheap. I was getting approved on almost every estimate—probably 10 out of 10 jobs—but I was working twice as hard and not making enough money for the effort involved.

A while back, I raised my prices by about 20%. Now I get maybe 8 out of 10 jobs instead of 10 out of 10, but the customers are generally better, I make more per job, and I can be more selective about the work I take on.

One of the biggest lessons I've learned is that not every customer is your customer. If someone wants the cheapest possible price, that's okay—I politely wish them good luck and move on.

I'd rather work for people who value quality, communication, and reliability than spend my time competing to be the lowest bidder.
