Video editing

I have some video footage that needs to be edited to be suitable for Social Media. We want 10-20second videos. We will need to add in logos, and some text.
For example, we need to crop the attached videos to isolate each individual Pilates Move, title it with the name of the move, add the logo, and add in credits at the end to say book today www.elitepilates.ie.
We will also need to add in music which we will provide.
It should look something similar to this video testimonial; https://www.youtube.com/watch?v=MSBVwB7wYec
