Add wordpress blog to existing web site

Simple project to add 1 page wordpress blog to an exisitng website (css/html) design. I want to preserve the exisitng style of the website, so don't want to use a new theme from wordpress. I have the page css/html code outline/style already done, I just need someone familiar with wordpress to add the blog. This should be a short 1 or 2 hour project for someone who knows what they are doing so please bid appropriately (I.e. low end of the budget range). Thanks!
