Animated Illustrations

I need five animated illustrations created for a how-to dvd that we are producing. The first animation would be about ten seconds and it would involve our logo being cut out with a saw and then screw to a wall with a cordless screwdriver and then the sawdust being blown off of it. The second animation would just be diagram of a room with an animated arrow that would move across the width of the room and then the length of the room and then a graphic that would write: Length x width = area The third animation would show a simulated piece of floor tile that would then have marking lines coming across it to show where cuts are to be made and would then simulate the cutting out of the areas within those marked points. The fourth animation would show a room with one row of simulated tiles being installed one-by-one the complete length of the room diagram and then the complete width of the room diagram. It would then show the following being written. Length x width divided by tile size. The final animation would be to show a diagram of floor tiles being laid with a narrow piece of tile left against the end point. It would then have a "not" icon (a circle with a line running through it) and would then show the tiles being installed so that the correct way to install the floor tiles is to split the difference between the starting wall and ending wall. The illustrations would be used within a dvd so they would need to be create so that they didn't lose clarity or begin to pixelate when shown a larger monitors. Each of these illustrations would be about ten seconds each.
