Create a jimdo.com-compatible website layout

Hi, I need a website layout that i can be imported into the web based Website Creator [login to view URL]! I will provide detailed information on how the website should be structured and how some items should be designed (e.g. the navigation bar). I also expect the contractor to be willing to answer question during and also after the project (for example: How can I change the background color of the navigation bar etc.). Thx, Jens
