add a third column to a two column wp template

hi, its a simple and quick job. you should add an other column (left) to the following page: [login to view URL] you can make the middle smaller about 150-200px and 20-30px smaller the right sidebar to make space for the left column. important! i need to add widgets from the back-office to the new left column. FTP and administrator user will be given once we have made the deal. happy bidding:) thanks!
