Native speakers to record simple dialog lines in English (North American)

For an educational project of non-commercial nature a set of simple dialog lines needs to be recorded by native English speakers (North American). (Ideally we’re looking for 2 female and 2 male speakers.) You don't have to be a professional narrator or actor or have access to professional recording equipment. Based on our experience it shouldn't take you much longer than 1 hour. Detailed requirements can be found here --> [Dialog Lines Recording: Requirements][1] Please note that being native speaker is a strict requirement. Please also note that at this point we are particularly interested in? North American (US or Canada) native speakers.
