Two 3d modeled and rendered videos - 1. Futuristic spaceship + 2. City of the future

Hi, For a sci-fi book trailer movie, I would like to have 2 short videos: a city and respectively a spaceship of the future, 3d modeled and rendered inside a background movie. The 2 videos should be of aprox 5 sec each: 1.- a spaceship of the future moves ahead, in front of the camera, having a movie with clouds in the background - Spaceship is not a small aircraft but a huge carrier/battle cruiser/cargo freighter. Examples here: [login to view URL] / [login to view URL] (thought I don't like the antenas) OR here [login to view URL] (though I would get rid of the two extremities with light on them) - movement can be something close to what is at this second: [login to view URL] I don't care too much about how the ship looks like or originality, as long as it looks real and big. - Background can be this movie, from second 10 to 15 [login to view URL] 2.-the camera moves up from ground and films the city of the future (in the middle of nowhere) from a distance - use this background from ~ second 7 to second 12 [login to view URL] - city occupies the valey; - aproximative description of the city, but it can deviate to any other city if is really looking from the future and seems real/well rendered on a background scene like from the example video: "The greyish-white of the metallic buildings and the modular architecture made out of cubic structures dominated the landscape. Civil constructions, pyramids hundreds of meters wide also made out of multiple cubic structures (each would have aprox 3-10m). In the middle of the city, in a quadrant huge platform, four huge, cube-shaped identical structures/buildings. Above, small fighting aircrafts hovering (optional). Between the four gigantic cubical constructions several hundred meters away from the center of the base, four cargo airships had been stationed—one against each building (these are the spaceship model used for the other video). ! PLEASE DO NOT BID IF YOU DON'T HAVE SIMILAR EXPERIENCE (SPACESHIP AND/OR FUTURE CITY) THAT YOU CAN PRESENT Thank you
