3D-animations for a short-horror-sci-fi-film (light explosion in space)

Hello, I am searching for someone who is able to create five animations for me: (1) The universe - black, but full of stars; far away in the distance a light spot gets slowly bigger until it explodes over the screen into multiple colors (a reference: [login to view URL] ; its from the film "Under the skin" and its kind of the direction, but not exactly of course - I need more colors for example) - 8-10 seconds (2) The same camera angle. What has been the light spot is now a drifting cloud of light (somewhat like the photo that I uploaded). In addition to this shot, I will film tentacles in front of a green screen. You will have to compose this material into the cgi shot, so that the tentacles come out of the distance (out of the cloud of light) - 4 seconds (3) The tentacles are closer to the camera now (apart from that it is the same shot like before) - 3 seconds (4) The tentacles cling round the cloud of light (I am thinking about filming the tentacles in front of a green screen and let them cling around a balloon - what do you think?); the cloud is pulsating and gets smaller - 4 seconds (5) Its kind of number (1) but in reverse: The cloud of light becomes a little spot again and then disappears totally in the blackness of the universe. - 6 seconds (but it would be cool if I got some more material of this shot - of the black universe with the stars -, so that i can roll the credits over it) Feel free to ask me anything, let's brainstorm about the effects and how we can create really bizarr images - out of this world so to say.
