I suggest that you take 70% of your time, and dedicate it to finding customers - in person.
Go to every company that you can find, talk to either the VP of Purchasing, or President of the company, and tell them what you have to offer. Your first priority is to get business in the door. Go to every bank president and business accountant in town and tell them about your firm.
Bring along some examples and pictures of your work and the shop. You are setup to do business person to person. It is how you got started, and what will get you busines going forward.
Expect to make 100 phone calls and 20 visits for every customer you get. Take careful notes and follow up on everything that is offered. It's just the basics of business.
Try to get your business setup so that no individual customer represents more than 25% of your total business.
