Small favor, if you're able - Looking for some feedback on some audio files

Hello folks,

I've been encouraged to work on my personal introduction and both 30-second and 60-second commercials for my coaching. So I got busy (there I am below, being busy with the microphone!)

I've spent some time on these and would love feedback if anyone could help. They're business-related so feel free to skip this post, please, but any feedback I can get will be appreciated.

This first one is (roughly) what I'd say if I met someone at a networking event or on the street and they asked, "So, what do you do?"



The next two are 30-second and 60-second versions of an "elevator speech". I attend a lot of meetings and networking events where the attendees are invited to stand up and give short intro (time is usually suggested by the host). I should have each version memorized but then be able to be comfortable not making it sound too plastic or commercial. But anyway, I'd love some feedback on these, as well.

The 30-second version:



and the 60-second version:

For those who wonder how I made the recording and added it to this blog post, btw, what I did was use Audacity (a free download audio recording program with a free utility for converting to MP3 format files). I used a low-end DJ-quality Alesis microphone, but otherwise nothing special. Then I uploaded the MP3 files to Box.net (a free online storage program) and used the Embed code for each MP3 file.

Thanks again, in advance for any feedback.
