small/short vs larger/longer jobs My business has been open for 4 years, so not nearly as much experience as many people here! But for me, small to medium jobs are where I make the most money. I'm getting really quick and efficient at those jobs, and they aren't taking up real estate in the shop for long.
The bigger jobs, like full interiors, are more rewarding. They are more of an artistic challenge, I love the process and creativity. But there's a lot more time in planning, consulting with the customer, etc. If there is any kind of delay, my main work bay is tied up.
The bigger jobs are while I love the business, but the smaller jobs are what make my business profitable. I usually take on a handful of complete interiors/large projects a year, and then fill in the rest of the time with small/medium jobs. It will all depend on your workspace, how big your team is, etc. I work by myself most of the time, with occasional part-time help and I find this works the best for me!
