Well, selling art takes work. You need to advertise in projects (since its not for money) find icon groups, etc. Putting a notice up here and on your page isn't enough.
You also have to understand that most of the people using this site are artists, and making an icon isn't really all that difficult. So you're going to have some trouble, anyways, you REALLY have to push to get noticed.
