Hi Charlotte,
Just had a quick glance at your site and unfortunately I couldn’t see any clear call-to-action message!? However, the good news is that I can see some low-hanging opportunities for immediate gain such as including a strong call-to-action headline on that slideshow. And just in case you need some further guide on creating effective call-to-action, check out this ebook from Hubspot (great resource for noob like us) http://www.hubspot.com/how-to-create-effective-calls-to-action/
Also if you decide to run a web experiment, I strongly suggest that you read this article http://conversionxl.com/what-to-test-first-second-third/ that explains what to test first, second and third (yep, the low-hanging opportunities again!)
Oh btw, I had a chance to check the site’s stats on semrush.com which apparently shows very low traffic volume?
All the best,
-Ashish
