Content for web page needed fast

I need 300-500 words of very descriptive content for a new web page. The web page's primary keyword will be "Houston web design". Please do not focus on surrounding areas of Houston. Just "Houston web design". I need a keyword density ratio of 15-20 percent and still have the paragraphs make sense and be very informative. Here is how I will pick the coder: Price (Lowest bid wins it - I rate high for good work) Past performance (Ratings on Rent-a-coder, examples of past work)
