short flash animation

Hi We have a small project involving an animation for a presentation. It is a 30-40 second long animation, basically 5 o 6 different screens part of the same storyline. Nothing fancy, and as easy to see as possible. Basically is a technician that plugs a wire in a computer, the data goes up to a cloud, then to a server where is processed and then sent back to the cloud and its downloaded by a guy in a computer where he prints a report of a guy he is sittin in his desk with. a couple more small details (such as product name, brands, etc) but those can be send when the project is awarded. please send us some samples of previous work, how long time you think you can have the animation ready and how many animation recorrections do you accept for your price. And if we want to add something on the future you can give us a special price.
