Hi,
I'm an expert editor and been into video editing for a few years now. I have gone through the youtube link you have attached. I can modify your video with texts, doodles and many more to make it interesting although your content is obviously a crowd puller. I created many educational/promotional, explainer videos, and many intros/outros. I have recently helped a client selling his house through a video advert. I mostly use premiere pro, Sony Vegas Pro, after effects, Videoscribe, final cut Pro for my videos. So let's start a discussion. I can edit your videos at $20/video. I can also do a sample 1,2 mins video If you like.
Thanks,
Rohit
