The centre part of any business web template has to be kept for showing off products or services. In the centre if there is a place the products or service with little description the users can easily understand what type of business you are running or what they can get from your site. So it is necessary that the layouts give you scope to utilize the space for attracting your visitors cum customers.
One option that many people don't think about is to use an article template. An article template gives you a general idea and then you have to insert the topic using the idea they suggest. For example an idea would be Methods for Saving X and a topic would be Methods for Saving Money. With most templates you will have the ability to do at least two articles from it until you can come up with more topics. The two articles would be a positive and negative or upside and downside. There are a number of places you can visit for article templates. Some of them supply free templates while others charge a fee for them. You'll want to do a Google search to see what you can find and use for your articles.
