Turn a Flash Site into HTML/CCS

Hey All,

This is my first time trying something like this, so bare with me...

Here is a website I designed to my liking, with a little more tweaking here and there it will be what I want.

Now before you pick it apart, here is what I'm trying to do: The site was designed on a Flash based template through Wix.com I don't plan on using this source, but I was able to build and design it to my liking.

Now, the questions is, how hard would it be to make this flash site to HTML?? What costs would be associated with this(not including hosting)? Etc. Also, since this is a real estate based site, would there be anyway, for the owner to update content??

Click below for the site:
Hess Estates

Any help would be greatly appreciated...and I will be posting this job on this forum eventually!

Cheers,
Jason
