Drupal Expert needed!

We have a site using Drupal that needs a few things fixed up so that it is usable and we can make it public. ## Deliverables 1. The first and most obvious issue on the site is the width of the left column area. At this time the left column overflows into the main area. This effects both the links on the left menu as well as the content in the main area. This needs to be fixed either by moving the column line, or making sure the text on the left wraps correctly. 2. The site consists of 4 main subjects/ topics, there needs to be a menu that leads to each - the link should show the articles from that category. The navigation should be easy for both between the categories and within each category. We need to make sure that navigation is easy on the site, so that a user can get view the content in each topic, as well as have an easy way to navigate to other topics. The end result should allow me to place my content in each category as I see fit, so that the user can find it. 3. Besides the main banner for the site, we also have a banner for each category/subject, and would like to display that banner when in the specific category (in addition to the main banner for the site) so that when you switch between the categories, the banner will change as well. This means that all articles of "Topic 1" should have "banner 1" and articles in "topic 2" should have "banner 2" ETC. The location of this banner would be right about the content (between the site banner and the content). We have the banners already so this task is specifically Drupal work. We are using a Module that allows us to place a different banner for different pages (called image header). It gets placed in a block and we need it to appear right above the text. Either fix this module so that it shows the correct banner for each category and shows up in the currect position- or if there is another solution that will do this, that is fine. It should be automated, this means that we don't want to have to upload the banner every time we add new content to the site. 4. We need to be able to add Google ads to the content area (See example here: [login to view URL] ), if there is a way to do this automatically, or easily that is what we are looking for. 5. Some CSS work is needed to change some links on the site. We need the links on the top menu of the site to match those that currently appear on the top menu of the front page.
