Hello.
I hope you're well. I certainly think I could offer a good narrative voice for it, considering I'm pretty calm and easy to listen to, and furthermore have the stamina to record long projects. I have a background in theatre and film, as well as music, having taken part in TV shows, amongst other things. I have a home studio, fully equipped with high quality microphones (I use a Rode NT1A for narration most of the time), and process it all through a professional digital audio work station (Logic), through Scarlett equipment, to guarantee high quality audio. I'm sure this is a lot of "gibberish" but, I feel it's best to give all the details.
I could get this done within two weeks from the starting point. The price includes high quality WAV files, commercial rights and full broadcast rights. I could send you a audio file and if you feel that my narrative style and voice might work well for your book, I'd be happy to do it. If I'm not what you're looking for, I totally understand and wish you the best with your project. Being a creator myself, I understand it's about what feels right.
Kind Regards, Alex.
