Customization of IdeaScale

Hi! I have an account on Ideascale(dot)com - which I would like to customize to have the same look&feel as our website. Inside my account on ideascale(dot)com there are possibilities of customizing both the header, footer and mainpage with simple html-editing. This is the site I want to customize: <http://tenknytt(dot)ideascale(dot)com/> And it should look similar to our website: www(dot)avito(dot)no I will provide login details to our account to the coder I choose to work with. If you have experience with Ideascale it will be a benefit.
