Actors needed - pure english

I need 1 actor (male) and 1 actor (female) to pronounce words and sentences in english. The purpose is to teach english to children. About 300 cuts each actor. Actors must have perfect pure english, good pronunciation, be nice, so can mantain interest of children. Video must be cut, delivering a file for each sentence. Candidates should send a little video pronouncing some sentences so I can check their skills
