Whatever it is that you do, create a website where you can show your work.
I've looked at several websites and Weebly.com is the best for me. It's free and very easy to create. Once your website is set up and you have some items or services to sell, market them via Facebook, Twitter, Goodle+, LInkedIn and Pin Interest. You also might want to have some promotional materials printed. For that I recommend Vista Print, they have the cheapest prices and their materials are really good.
As with everything, perseverance is key. Good luck.
