There's loads of work out there if you are any good, so you don't need
to cover all bases. I'd think about which sort of work I most enjoy and
move to specialise in that, joinery, roofing, plumbing, electrical
repairs etc whatever. Then kit up appropriately. Jack of all trades
master of non - and also you tend to get lumbered with crappo minor
jobs which although easy to do are difficult to do economically,
especially if you've had to go out and search for a particular
component which can take all day.

bet of luck
