Try going to a few of the sites where Spinning instructors hang out such as:

www.turnstep.com

www.pedal-on.com

There have been quite a few profiles shared at those sites. If you haven't considered actually getting certified as a indoor cycling instructor, that would be best. Although it's great to be an outdoor cyclist, it doesn't automatically transfer into indoor cycling because of the bikes themselves, the flow of the class, the number (and there are many) of non-cyclists that attend the class

I'm an outdoor cyclist, but also am certified by three different organizations to teach indoor-cycling/Spinning and have been doing it for about nine years.
And I'm still learning all the time. I also own my own personal training business, and believe me....Personal Training really doesn't really prepare you to teach a group fitness class...(at least it didn't for me). I love one-on-one training, and I love teaching Spinning to groups, but they are soooo diffferent.

Good luck and have fun teaching the classes. It's a great way to introduce people to cycling. A lot of my members have ended up buying bikes and taking their rides outside.
