First, your site is beautiful and does many things very well.
Your biggest obstacle is clearly the price point. You say it's being marketed as a premium product. However, aside from the fantastic photos, there's little that conveys that message. Your bullet points (which are great for quickly conveying the message) simply list:
-5 drawers for all your makeup and beauty products.
-Quickly access your favorite makeup and beauty products.
How does that make it any different than the <$100 products on Amazon?
While I'm a big advocate of using bullet points in all descriptions to perk someones initial interest (as we know, internet users are largely scanners, not readers) you should have a narrative description to really get people excited about the product. Something like "Ladies have you been looking for the most elegant makeup organizer in the World to compliment your glamorous lifestyle?". You can pay some fantastic writers on elance $50-$100 to write a fabulous description. (btw, if the world's largest etailer, Amazon, uses both bullets and narratives, you probably should too)
It should be said that you're fighting an uphill battle. People generally shop on the internet for value and to save money, not for premium items. That's not to be said that it can't be done, it's just a lot tougher than hawking a $50 piece of crap organizer. Also, as it looks like you have a wonderful product, I hope you're considering other options for distributing the product, such as brick and mortar stores.
Some other general points:
-There's no phone number. Possibly you're working a full time job or have other time commitments that don't afford you the luxury of answering the phone all day. Put an 800 number on there even if it goes straight to voice mail promising to call them back within 24 hours (don't be afraid to be honest in your voice mail message that you work full time). For the 1% of people who want to talk to someone, it'll at least give them the avenue to do that, and for the 99% of other chickens out there like me who don't want to talk to a real person, it at least creates some trust.
-IMO, there really should be a picture of a the organizer actually organizing some make up, other wise it's difficult to quickly understand what it does.
-Sell the product on Amazon as a third party seller. It might not be your ultimate vision of how you want to distribute the product, but it will answer a lot of your questions. If you get a lot of Amazon sales, then your website design is the issue, if you don't get any, it's likely a value/quality perception issue.
