Without regular, persistent, thoughtful marketing, most freelancers would not last long out of regular employment.
So don’t forget to market yourself. You are a brand, a business and a person. All three are marketable. Some people shy away from marketing, perhaps because it sounds too American and corporate, but to me ‘marketing’ just means telling people that you exist. If you’re offering a good, professional service there’s no reason why you shouldn’t let people know.
