Good advice. If a customer looks after his tradesmen, pays well and on time, they'll look after him. The inverse s true also.
Save yourself the headaches of doing it "cheap" and take on the mindset of doing it "well" with maximum efficiency. Look after your workers and pay them fair rates and you will reap the benefits of their satisfaction of fairness from you. Everyone enjoys a fair go so enter into this spirit. Tradies dislike misers and bargain pushers and will lose interest in their work if a customer is miserly.
I could go on with more advice but, I guess, you will soon learn once you get going. Everyone here is providing good advice based on their experience. It's up to you if you want to make the same mistakes we have made in the past before accepting the advice.
