Animated Websites

I am looking to put together 4 small websites (all with the same structure) each with a 30 second cartoon-style animation as an introduction (happy to consider other ideas and solutions) I will provided the voice over for the animations. I will also look at adding 2 or 3 powerpoint style annimations. i want the design to be clean and simple - ideally not flash - but im happy to be guided. I have attached the voice over and animation plan for the first site. Site Summary Animiation Introducion Opens to a website that contrasts the how inexpensive and easy to have your bookkeeping done against the lifestyle cost of doing it yourself. Website should be clear and unclutered. Should contain clear images Should highlight our bookkeeping packages Need a simple calculator - to give a quote (they will need to register for this) I have five of these to do - they will be basically the same (except the themes and animation) I am hoping that each will cost about $300 - Please make sure your bid is for just 1 site. Happy to discuss pricing options.
