HeavyBubble focuses on artists with a simple website builder that is unfortunately too expensive.
$20/month will limit you to 40 published images, you'll need to pay $70 per month for 200 images. Plus, there's no ecommerce capability. They do offer email newsletters and promote their artists on a section of their site called "Artlife", but that's not enough to justify the high price.
The free trial is not instant, they need to get back to you with details for access.
