youtuber for a kids channel

I'm looking an English female with a nice voice to tell things and sing nursery rhymes to kids (2-4 years old kids) as a youtuber for a kids channel. I will pay per hour as an English class. 
videos will be recorded playing with kids, you only will show your hands, and of course your voice.
Videos will be recorded during the weekend in Madrid (near Metro Avenida de America)
