I am looking for recommendation for a powerpoint designer to put together a slick professional powerpoint presentation for a seminar I am teaching at later this month in Florida.

If you really want to make an impact, I would recommend looking into Prezi - Presentation Software (http://prezi.com)

I do lots of presentations and used to do even more back in my marketing days. When in a bind with really big presentations i often found hiring a pro through sites like odesk or freelancer to work really well. Most of the time i could get a really well done presentation for about $100.

As one of OKC's TOP 5 ranked ad agencies, my company (www.syn3rgycreative.com) does custom professionally graphic designed presentations all the time. Let me know if I can help.
