Dubman yeah you definitely need to be working for yourself, customer based rather than site hut even a couple of years on with a domestic builder/company would be great experience if starting out. Even if you learn what not to do
Most of my customers are repeat plus I’ve got a couple of landlords and 2 estate agents who keep my busy too.
Know what you mean about the back. Fell off a ladder a few years ago and now have to be careful what I’m doing as one wrong move and I’m laid up for a week
