Work out all your costs, then add about £100 pw for the bits you’ve forgotten, then work out how much the least you can pay yourself is, do this several times, then ask yourself if it’s what you really want. If it is, then shop around, to try to get everything for the best price, when you have that knowledge, run your figures again, work out your pricing, find yourself a yard, provisionally, and make sure you’ve got all the necessary criterion for an O licence in place.Then begin to quote for work, if you get a bite, then buy/lease a truck and trailer, apply for O licence, with an interim, and get going.
