Web site design

I designed a basic website in iWeb to market our boat which we charter in Greece but it cannot be seen by any search engine and can only be found if you type in the exact url address to the address bar. I would like to get the site design updated and extended maybe to about 10-12 pages and put into a format which I can update and change as required. I want to create a fresh looking web site, suitable for marketing a greek sailing holiday. I also want to make sure that the site is fully search engine optimised and incorporates google analytics. I am NOT looking for onsite web availability and booking.
