What would I have to do to get a higher google page rank?
thanks.
Besides the very limited <title> entry which is missing a geographic target, i.e., your business location, city, state. Where's the other major SEO metatags– <description> and <keywords>? They appear to be missing.

Here's a helpful tutorials on setting up those missing metatags:

The second metatag is the "Description" which is
usually 25-30 words to form a complete sentence which
best describes one's goods and services.

And the very last category - "Keywords" are also
somewhat limited to 15-16 words which can be plural
and compound in nature. Again, avoid multiple entries
which could be mistaken as "spamdexed entries" which
is defined as the loading, and submission of
repetitive words into a particular metatag category.
"Spamdexing" when discovered on a webpage and reported
to Google's spamreport.com can result in the
elimination of your website from their search
directory.

Good luck!
Why so much adsense on your site. I would not put it on there until you have more content and traffic. It can affect your rankings. Your site if this is your first one is ok. Personally you might want to go with a hosted wordpress site if I were you.
