Hi,
Firstly, this project sounds great, I love reading horoscopes, but the variety of the other things looks great. I run a recording studio, based in the South West of England. We produce radio ads, audio books, podcasts etc... and because we have a variety of clients already, we have different voice over artists we can use, depending on the need. If we use in house, I can turn a project like this around for you in 24 hours usually.
As an audio person, we tend to be perfectionist, so during any collaboration, I am always in contact to make sure the client is happy with final production and mastering. I have put 2 demos on my profile, have a listen. If you want a specific sample for your project, I can do this for you to help you make up your mind.
Really hope to hear from you.
Phil
