Video editor required to complete around 50 30-90 second clips

We had a range of exercise instruction videos (gym exercises such as squats, running etc) shot a few months ago. Unfortunately, the videographer did not complete the job as paid for so we have been left with around 50 short videos that need to be edited (some may need voice overs, audio cleaning and/or subtitles) before being used for e-learning and other marketing uses.
They are in mp4 4k format and around 1-3 minutes long. The edited results should be around 30-90 secs per clip depending on the exercise and with company logos and clear voices.
A sample clip can sent privately to give you an idea of what you'll be working with.
Thanks
