hay - I have gone through the website fully, checked almost each page, there seems to be alot of issues - I would recommend you to completely revamp the website and upgrade the CMS to a leading open-source CMS known as WordPress - more and more people are moving their website to WordPress because its easy to use, SEO friendly and powerful.
I would want to improve the design of your website as well - what about completely redesigning it?
