Town plan, park and landscape computer generated artist impresions

I need a number of computer generated artist impresions of a community project on parklands, with structures, art murals, railway, trains, etc. possibly have a 3D walk around feature, or video? and approx 10 to 15 stand alone impressions of plans and elevations of entire project including specific items/areas of parkland, structures, railway, and other key features. We will send photos of existing area and point out where we want new structures, items, murals, shade sails, walking paths, etc. This we believe will require large amounts of communication and acceptance to change from our awarded freelancer. Must see examples of your past projects before we will award project.
