The only way this will work for you is to promote it every where you can. Marketing yourself is key to making sells. Don't expect them to magically happen. No one will buy your work until you let them know you have work for sale. Use facebook, twitter, google+......the list of social networking sites is a long one. Pick a few that you enjoy and start showing off your work. Link your instaprint URL to them to direct people. Good luck.
