Hi Minna:
Site looks good to me. Is exposure your primary concern at the moment? There's lots of reading that can be found on SEO at Google
http://www.google.com/webmasters/ they would be the authority on on their search engine.
If you are not very "computer technical" you can always hire out an SEO expert. I'd start by contacting agents who are where you want to be in Google and ask them who they used. Of course I'd ask agents here on this forum and not in your area of business. Chances are they won't want to give you their competitive edge. You'll get more honesty here in this forum.
Kind regards.
