Submerged Sea lagoon construction animation

Please review the Youtube videos given below for type of work I'm looking. The video shows how the wall construction is done for the lagoon and how the turbines are placed to produce electricity, when water level changes. I'm looking to make similar video with little changes in addition to that. I anticipate video less than 60 second long. Let me know if you can make the video as shown in below samples. Provide only relevant (water projects) samples. [login to view URL] [login to view URL] When you bid, tell me how you will make this animation and what software you plan to use. I don't want generic proposals. When you bid, provide actual amount and not placeholder amount and write "Sea Lagoon" before writing proposal, so I know you understand what is work. I will ignore proposals without "Sea Lagoon" keywords. The plot is like this : We show Earth and moon revolving around it, then we focus on earth and zoom to the lagoon. Then we show how the wall is constructed. How turbines revolve when water level changes from either side. We don't need to show people moving. If you have any questions let me know.
