Short Showcase Video Editing

I need a video putting together to showcase my classes in my fitness business (currently online) - approx 60s in length. I have about 8mins of content currently sat in IMovie, plus logos. The content is short clips of me delivering each class type - I will provide details of the classes and the information I need to get across. I envisage a split screen perhaps with video one side and words the other.

I plan to use the video on my website (www.adastrayoga.org), YouTube (Ad Astra Yoga & Pilates), Insta (adastrayogapilates) & FB (@adastrayogapilates).
Would also like a condensed version to use as a FB banner.
I have been producing my own videos/Reels etc, but I lack the skills for a professional look!
