It's hit and miss with marketing. Whatever you do don't stop even when your busy. Get the work then decide how you want to do it. Don't quote over the phone, show people your professional, got out and meet them. Show them what you do, what you use, get testamonials, photographs of previous workmanship in a folder. Don't try and get work on cost. You'll never compete with weekend merchants, splash and dash, and people on the social.
