But for that to happen, you actually need to be talented and create amazing work, since it's a lot easier for a curator to push for you if you create something that's compelling.
If you look at the works in the elite galleries, the artists that are represented by them are much, much better than your everyday artists that you'd see at your local art fair.
So, the process is:
1. Create some awesome art.
2. Show it someplace - could be in a local fair or student exhibit or on the internet someplace.
3. Have some people talk about it by sending out press emails.
4. Get a major gallery to notice your work. The good galleries are always on the lookout for new, marketable talent, and if you have some buzz, that helps influence them.
5. Profit.
