Twitter Image and Placement

This should be pretty straight forward. I have created a new Twitter page. I need a background and small image that will be positioned to the left hand side of the page. I have a solid example of how I need this to look. I will provide the content (words for image) and the hex colors needed, etc. I also need the freelancer to add the image to this page as I don't have the time to fiddle with it. This should be pretty straight forward foe someone who knows what they are doing.
