Ask HN: how do I get in front of art collectors online?

Hi HN folks! I recently launched a website selling art online. All of our artists are Brooklyn based and so there's a strong local component to the business. All the work is original and ranges in price from $150 - $12,000. While we've had some success and momentum I'd love to ask the collective HN brain: how do I get in front of art collectors (or people who might want to purchase art at this price range) online?
