30 second voice over recording (wav)

I am looking for a voice over artist, professional or beginner, to help me with a short clip that I am looking to make to help a small marketing project that I am currently working on.

I am looking for a clearly spoken - reasonably mature, person who can produce a recording via their home set up. The quality only needs to match that of a phone call - so this can be replicated by recording directly into a PC... a sample would be needed. Thanks
