What I do is mindful, exacting, OCD to fit and finish of whatever the job entails- in general, a conscientious employee.
Employee is, might come natural to you, but I would think along the lines of being your own boss.
How artistic are you, attention to detail is a very good quality.
A very easy business to start is a in home service (On Site) since you can work out of your home as your business address. I'm a furniture finisher and have been working for my self for most of my life with 38 years in the trade. Now furniture needs to have a shop to work on it, architectural wood work not so much.
But there is also work in just touching up furniture and architectural wood work in people homes on what they already own. Have kit will travel fixing little nick and dings in nice homes and cleaning up the built-in wood work. People with nice large homes have a maintenance cost that a lot of don't think about. They want their stuff to always look nice since they spent a lot on it.
I get a lot of calls just to touch-up kitchen, most of the time the bulk of the work and what looks bad is just a need of a good washing. That gets me 85% there, then take care of any touch-ups that need to be done, I alway tell them just my cleaning is worth my cost.
I work by the hour when I do this, so while I have my foot in the door you can get more work from them. Point out that you can make other appointments and run though their house taking care of needs on the furniture. You can also point out that a good cleaning and care of the built in wood work will make it last a lot longer, saving cost and disruption of remodeling. The next thing you know your there three times a year taking care of things. This is building a clientele and word of mouth starts to play in as they tell a friend.
Another job along these lines, hooking up with contractors building new and remodeling homes. The last people in these homes doing work is cleaning business, the painter touching up and me touching -up wood work. We are there fixing protection damage from tape and other things, construction dirt and basically paying attention to detailing out the house so the contractor can get paid.
I have thought about a business like this when I don't want to do all the heavy work any more. Instead of the contractor needing a cleaning business that can also do damage to the wood work, and a wood touch-up person. Combine these two steps that can work together hand in hand going though the whole house. The cleaning crew can be instructed as to the needs of the wood finisher saving damage and shortening the time the skilled labor is needed.
Some of this stuff might work out good for you and your wife and you all could be a team to start with. Starting a small business like this doesn't cost a lot and tax write offs at the end of the year can be a lot less than you ever paid in your life.
