My initial impression is that your site has lots of ways to leave it and very little content to keep people there. Are the spas you link to paying you a commission? If not, why the links?
Have you considered offering music samples so that people will stick around and find out what they could get? Maybe you could team up with local artists or photographers to pair the music samples with relaxing imagery.
(I see that CDBaby has music samples, but the link to it emphasizes the price, not the ability to learn more.)
