3D video presentation

Hello guys, I need 2 videos for presentation of mobile application. First one will last 45-50 seconds and it's intended for individual users, and second one will last about 80-90 seconds (it's for business users). Both videos could have the same style, both will have some background music and both will have the narator who will talk about the product. I will choose 3 the best freelancers and send text for the videos, Then you will read it and give me your idea how you would make it, scenario which describes scene by scene. Here you can look at one video which could be a good example, but our videos have to be much stronger and effective, with more elements and some 3D effects. [login to view URL] Please do your best and on the begining of your message put code "temo", in this way I will see you have saw the all requirements. Messages without the code I will not read. Please not that you will make videos only in English, but we need all files so we could translate some words to another language in few steps and put another languge naration into it when we will need it.
