If your customers would like a more professional site they would jerk off looking at your banks homepage!... the models sell the tour and even the crappiest of tours convert better than the most professional ones!
btw.. the tour pictures break apart on my box running IE7:

The first wanted response from your customers is to get them horny at the tour. You don't want them to feel like they are in a clean and professional clinic.
Dump the new tour and put the old one back. If you turn it into an AVS it will bump up your rebills unless you already have tons of content
