Hi there
I'm an experienced voice over recorder and provider. You say in your bid that you don't need professional quality, but I have a studio quality mic and I use Audacity to ensure that there is no background noise.
As an English teacher in the UK, my own pronunciation is extremely clear, and I have provided educational and training voice overs for companies in several different countries - and can provide samples on request. I also have access to a large number of colleagues here in the UK, so that you can get your recordings in different voices, with the different moods you have requested, done professionally and clearly.
Please get in touch to discuss further - I would be very interested in providing this service for you.
Kind Regards
Simon Richardson
