Use the free siFR developed by Mike Davidson. Many professional sites use this, including corporate sites. You can see an example at my site Impress Lab. H1 and H3 headings have the siFr fonts.
Basically what it does is you have a normal html page with, for example: <h1>Page Title</h1> <p>Page text goes here.</p>
At the end of your html is a Javascript that converts any text between h1 (or h2, or h3 or whatever you set) to Flash and a Flash font, such as a script font, on the fly. Read the tutorial on Mike's site; it took me about 10min to set up on my site. Go to http://www.isarie.com/?p=17 for siFr fonts; you can also create your own from TTF fonts (search the web).
