Flash Search Engine Optimisation

Hello people!
I have a pressing issues with a website I did in full-flash.

It’s a corporate website I just completed - www.tsa-solutions.com

I do realise that most search engines cannot index flash sites/files, but the client never told me the importance of their website being searchable by search engines, mainly google & yahoo, so I am kinda stuck now that none of the search engines are displaying results when you try searching.

The whole site just went LIVE only a couple of days ago, and here’s the few things I have done to try improving the searchability:
[LIST]
[]added a meta tag with plenty of related keywords
[
]added a <!-- sample text --> to the <head> of the html index page
[]added the url to google, yahoo & msn search sites
[
]used a few FREE site submission tool to 75+ search engines[/LIST]
And here’s the list of things I am going to add, from where i have read from some articles that MAY improve the searchability:
[LIST]
[]adding a meta data in flash 8 capability to flash files
[
]adding a z-order layer in html files underneath the .swf ( http://www.pagetraffic.com/guide/flash-indexed-search-engines.php)[/LIST]
I would so greatly appreciate your opinions on this? Have asked a few people but they strongly suggest I re-do the site to be a hybrid flash + html pages. That is the last thing I want to do coz then I look really stupid to my client…

Thanks guys!
