Flight school GoPro Videos

Hi I am the manager for Everheart Air simply looking for someone to edit our videos it doesn't have to be super fancy.
As our business grows we plan to send more videos to you we are falling behind in this category and currently have 13 videos that need to be done. I have an example of what we are looking to do for our customer.

If you need more examples check out our interview @Everheartair
I did this one myself on Davinci Resolution. What do you think is the lowest you could do a videos like this for? how long would it take? if I sent you the footage with the songs they want put on it? It only took me 2 hours to do the video and if you do it right we can send you the other ones to do
