Keywords are of dubious value for today's search engines and over-use of them can be detrimental to your ranking since keywords that don't have relevance to text on that page can mark you down. Search engines take more notice of the text on the page and you seem to have this covered quite well on your home page. <h1>, <h2> tags are also important but you have used quite a few empty <h1> tags and have an image inside another. Images can't be read by search engines and you don't even have any 'alt' text for the image which might have helped a little.
I copied the keywords from your home page into Word and it counted 1371 characters. Don't forget that a character is any letter, number or space not just full words. You also seem to have the same keywords repeated on each of the other 7 pages.
I would suggest greatly reducing the number of keywords on the home page and deleting them from all other pages or at least reduce those on any page to be relevant to just what the content on that page is.
