Hi
First impressions of the site is it loads fast and looks good. When the homepage appears, personally, I would like to see some more product images and/or links. Im not sure what the main focus of your site is, but from first looks I may think it was a climbing info site as appose to an e-shop. I think this is because it has a lot of text, and as I said, few product pictures.
Do you have site stats as to how long people stay on your landing page/site for? Its usually a good way of finding out where there may be a bottle neck.
Have you made any progress with orders yet? Have you tried any Cost per Click marketing? i.e. google adwords? We found it a highly effective way of driving some good (relevant) traffic to the site and generating some orders. If you were to do it, I would suggest many different adverts and having them link to specific product areas or products i.e carabiners.
You have lots of great products, Im sure a bit of site tweaking will bring those orders in.
If you get a chance check out our site
www.skatewarehouse.co.uk, similar market (i.e. specialsed action sports)and see if you can get any ideas.
