Hi Dan,
Quick ones I noticed, add some keywords to your meta content. Get away from using tables, use DIVS instead and maybe re-think the header of the webpage so it is abit more towing orientated. Half the battle of websites is linking the theme of the business to a theme of the website.
Also look into ensuring whoever makes your site uses Header tags, alt tags and title tags appropriately to help with google better.
