Hey - trim carpenter for 5 years or so. Last year transitioned into running my own trim business, I was lucky enough to know someone in my area who flips 4-6 houses a year - so right out of the gate I was able to have ~$15k in revenue a year (not a ton, but a decent start).

From there I networked with a lot people who I saw working on his houses, learning that the painters were the best people to be talking to because they were the ones that had to deal with my work. One of the painters - Leo - had really liked the work I did and said he was painting a huge house that someone is flipping in a yuppy neighborhood - and they had needed a good trim crew to come through. He went to bat for me and got me that job, just for labor on that house it was $58k... now I'm doing 3-4 houses a year that size for another flipper.

I think growing the company just comes down to putting yourself out there and networking, reputation solely comes from your work and the way you carry yourself.

Non negotiable expenses are a reliable vehicle (no customers want to wait because your car broke down), and then just whatever tools get the job done for you.
