Hi Leander,
I do web design and freelance writing. I gained a lot of contacts and help by joining my local rotary and chamber of commerce. You can attend chamber "cocktail" hours and make friends with area businesspeople. Take some nice business cards with you and have your business description prepared that you can describe in 15-20 seconds. Sell yourself and make sure you know your business inside and out. For me, creating a freebie website for a small business helped give me more status as an actual working web designer and the word of mouth helped tremendously. Marketing and promoting your business should take up half your time at least in the beginning. Study the competition and see what they use for marketing their business, especially the very successful ones. Create a professional image and be faster or better than your competition to make even more of an impression.
Good luck!
Anne
