Design for travel planner site

We are looking for a design for a Travel Planner site. The wireframe for the site is attached. Usability of the site: step 1: Filling in the place of departure and destination step 2: Filling in time, date. step 3: Select mode of transport (multiple options possible) step 4: hit the search button step 5: on the left side of the map the different possible routes are calculated with time and price. Then it is possible to click one and the details of the road become visible on the right side over the map. Before completed step 1, step 2 and 3 should be invisible or disabled. After completing step 1 they should become visible. We want the design of all the steps visible and only step 1 visible. The squares for the way of transportation can be filled with icons. Like a bus for example. We are looking for a clean design with no bells and whistles. A bit like the previous version of google maps. Kind regards, Benjamin
