Paul,
Check out my site:
http://www.sfx-clan.com for an example of a PHP based CMS system implementation, with over 100k unique hits a month. Based on the e107 CMS system. I point you at this site, as it's a working site, i.e not just an information portal.
I was over at your site recently, which is a nice bit of Flash work
As a proffesional web developer I have worked for some big highstreet names including Orange Mobile Phones, Vodofone, HMV to name a few. Developing point of sales applications using web technologies/ Unfortunatly much of the content developed for these guys is under NDA and I am unable to show you it =(
I am fluent with all the macromedia MX suit, Flash, Director, Fireworks, Drumbeat and so on. I am available Freelance and can forward you a resume if required.
Edit: pHrEaKzOiD is my non-GameStudio name
Edit2: I just remembered a Flash based sample I made
Check it out Here Please note the pre-load is not set up perfectly so you may need to refresh it after the first run to see it running smoothly - This was just a test and so never went further than this
