make a showreel animation for my product for developers

I have a product...a folding bike rack... that has been designed by a technical engineer. I need an animation done of it being assembled and working so I can show it to developers as a working model. The rack has attachments that can be added so I want clips of these too. The animation will show the bike being used in a few different environments, some examples: country roads, country paths, off road track, on a cycle route like the Embankment in London with Big Ben in the background. At the moment there are 11 scenes with 9 different themes. Three of the nine will just be a “green screen” plain neutral background. The whole presentation taking about 1-2 minutes long. An NDF...non disclosure form .....must be signed......please go to this link for an example of the type of animation that I have in mind
