If you can work in your shed and make things like that bunk it can pay ,but it takes time to get up the business. you do need to put that unique twist on it and live in a city to keep the freight down and a local market ( maybe not with the internet.
youd have to work real hard on getting one job after the other finished and away.
also gonna have to keep up with the paperwork rather than leaving it to wifey.
however ,the next few years are gonna be so focused on the business, will you have time for doing stuff with the kids , so youll have to factor in strict times for them.
I always try to go and meet my kids at school when they are in primary, and try to involve them in projects for a little while after school. on weekend it is harder as you want to use that time for your latest project,
so there are sacrifices. but the rewards can be brilliant
