FIRST: Unless you can stay in business painting 1 bedroom at a time for $500-$1000, which you can't, then you will be taking on several thousand dollar contracts that require thousands in Labor and Materials to fulfill the order. Multiply that by 3-4 jobs at one time or in our case 15-20 jobs at a time, YOU NEED TO TAKE DEPOSITS!!! It is horrible business not to take deposits. There are many jobs where its not possible to get a deposit and that is built into or pricing accordingly. If we are not getting a deposit, there is a finance charge built in, contractors are not banks. If you don't have a good feeling about a deposit, your hiring the WRONG CONTRACTOR. Hire people you know or well established businesses.
I do not mean to come off with an edge, however, this is an article for people hiring low bid, uninsured, one man band painters out to "hustle" a buck. Hire reputable, established companies or hire someone you know or have a strong referral from. If you are arguing over watered down paint, ticky, tacky deposits, buying your own supplies, you have hired the wrong guy.
The Lead Renovation, Repair and Painting (RRP) Rule establishes requirements for firms and individuals performing renovations, and affects contractors, property managers, and others who disturb painted surfaces. It applies to work in houses, apartments, and child-occupied facilities (such as schools and day-care centers) built before 1978. It includes pre-renovation education requirements as well as training, firm certification, and work practice requirements.
