Condition of the home improvement business, the trends of the industry and the business opportunity in the home improvement business.

The condition of the home improvement business, the trends of the industry, and the business opportunity in the home improvement business have all changed since the Recession hit.

What you had is basically an introductory paragraph: a paragraph that give the reader an overview of what they'll be reading about. Just change/tailor the ending of the sentence to fit the your paper. The ending part in a way states your purpose of the paper. In the example I gave, your purpose would be to inform them of how those three parts of the home improvement business have changed since the Recession.

After the first sentence, go into a little bit of detail about those three areas or somehow tie it into the next paragraph, which will probably be about home improvement part one: the condition (part two: trends, etcetera).
