Hi Clare,
Just had a quick look at your site and the first thing I noticed was that there were very basic page titles. If you can, change the content within the <title> tags in your site code to better describe your service as search engines pay attention to the content of these. However, I notice your site is a template and they may not allow you to change these, I have a feeling they may be automatically generated by what you name the navigational buttons to the left on your page.
If this is the case, you will be unlikely to get many direct hits from search engines. My advice would be to get yourself listed on as many free directories as you can, to build up links to your site. Perhaps also at some point consider investing in a professionally designed site which is better optimised for search engines, or invest in some pay per click advertising such as with google adwords.
Hope this helps,
Sarah
