Launch System Animation

I need to make a video editing/animation clip about 30 seconds long. Using a library of SpaceX videos of a rocket launching moments I would like to add the details into the original sample clip. Details like adding the building structures around a Falcon 9 rocket, also reposition the rocket horizontally and hoist it up into Launching position, changing the landscape around surrounds to a Moonscape or Martian background. Also adding two short "mechanical" details. About 5 seconds long or so. The scale is approximate and visual effects could be semi-realistic. The overall objective is to make a clip of the newly invented "Launch System", invented by me, which I would like to post on Elon Musk's Facebook group in order to promote the idea in His web sector. So, maybe it is worth some consideration from Elon's point of view.
