Building a solid business word to mouth is best. Realtors look always for good licensed contractors. You or your wife can call real estate offices and ask to make a representation at a meeting, hand out your cards and prepare a list if your services. Or drop off your cards with a list of your services to be put in the Realtors mail at the offices.  Back it up with good work if you get the opportunity. Stick to a schedule and finish the work before taking on more work. Quality service and promptness are important to grow any business. Know what is expected if you. Communicate. Don’t agree to do something that you do not know anything about. People appreciate your honesty rather than you doing a poor job.
