On a side note. You may want to invest in a better graphics program to make your tables and stuff on your website, as they are very fuzzy. Image is very important when you are selling advertising.
Colemg01, I agree.
Is it your graphics program, or too low a resolution. Do the images look better at a higher dpi?
On the pricing page, as are you are using a table-based design, why not make the pricing a regular table, rather than a gif. It would look nicer and be easier to change.
You need to have better titles. "Home" for the home page, etc you need identity and titles are important in seo. Put in your company name on each page, and succinctly what your company does, and for each page, what that page is about.
