Hey Amanda
I really like your logo and the website is good. Your products seem fairly high end so you would need to target people with money!
It seems like you’re not getting the right audience to your store which is why you’re not getting conversions.
Have you tried registering and connecting your store to channels like Facebook, Google Shopping and Upurr?
I would recommend connecting to Upurr if you haven’t as this is a pretty new tool that drives targeted UK shoppers directly to your store and also offers in app purchases. Its free to register and connect and only take 10-15mins.
You say you’ve spent thousands on Shopify Experts, do you know what insights they discovered regarding your marketing strategy? Ensure you get as much information as possible from them regarding what information they obtained in their efforts to drive traffic.
Hope you start getting conversions soon.
