I have been examining your project and I believe I can deliver nice Spanish (Castillian) voice-over for it.
I offer my personal home recording studio, which is ready and equipped with a high quality gear. I compose music, which is to say I take care of every stage of the production stage, from recording to mastering, that's the reason my voice-overs always sound top-notch.
About my voice, I took a 9 months radio course during which I learnt about voice marketing, interviewing, diction and timing. After that, I worked in my own music program in a local radio for three years. I do not own any particular regional accent, but a pure Castilian register. I am 36 years old, my voice sounds deep and warm. Please check my portfolio to listen to some audio samples, but it wouldn't be a problem to record a sample of your text so you can check if my voice is what you are looking for.
It would be great to have a chat with you about your project!
Best regards, David.
