Record video testimonials from 6 different people

I need 6 video testimonials with good sound quality from 6 different people without glasses about improvement in eyesight after doing eye exercises. The total text of all 6 testimonials is less than 500 words, some has 1 sentence, others 5-6 sentences, and will require 4 males and 2 females in the ages of around 30. The video quality can be with a phone or camera in landscape mode. The people need to seem authentic and flowing with their testimonials without necessarily stick to every word in the script.
