i liked the idea, but max keep in mind , ur first page should not be flash only, sometimes we use flash intro as our website main page but these are not SEO compatible, so to get good rating in search engines we have to take care of lot of things while developing, your task is simple but time taking, ive to study your industry alot more to give you more acurate proposal, if you are interested tell me so i can give you final proposal, keep in mind we can promote your site for free ( web SEO)
