Wow, who do you take us for? Bleeding appendages?
Do you have a sketch or a link to your page, so we can check out your code? Or are we to devise it for you from your description?
Curtain rises. Up music: theme song to JAWS plays in the background.
OPTION 1) Build the site in Flash. This will significantly limit your target audience to only those people who DO have Flash player installed on their web device and who DO NOT require web assisting technologies such as screen readers or language translators. You can pretty much eliminate all iPhone, iTouch and iPad users from your target audience. Also because Flash sites are poorly ranked on Search Engines, your site won't get any traffic unless your client sinks a boat load of cash into Keyword Advertising.
OPTION 2) Build a flexible height page in DW for the majority of web users who have various devices and screen sizes. Use plenty of keyword rich content in your X/HTML markup for SEs and translators. Add style to your site and layout with CSS rules, CSS Pull-Up menus and where absolutely necessary, Floatbox or Shadowbox scripts for modal window content.
Good luck with your project,
Good take, Nancy, are you going to do the screenplay in Adobe's scripting engine?
