If I were you I wouldn't start up again unless you seriously reevaluate your entire business.
Start by making a business plan. From there get properly licensed, bonded, and insured. Then maybe do a little bit of research. Learn about the business. Remember knowledge is power. Then do some marketing. You can start off by offering a first time special, but then raise prices from there. Walk around and talk to homeowners; be a salesman. From there you will gradually build up clientele.
There is a lot more to it, but this is a start.
