Professional Editing for Fitness Testimonials

I need a professional video editor to enhance customer testimonials I captured using Videoask. Each video is about 90-120 seconds, discussing their experiences with my coaching.

Here's what I need:
- Primary videos: Minimalist style with plain backgrounds, Casual tone.
- Captions: 'Heading of the question' at the top, and standard text at the bottom as captions.
- Secondary content: Shorter clips (10-30 seconds) for potential Instagram posts.

Your role is to refine my basic edits into simple, clean, polished videos that can be used on a landing page.
