Video Editor

I am starting 3 youtube channel subjects. I will also want to use other social media. They are about Movies- and whether they are worth watching, Traveling and how to do it cheaply and worth it, and Healing or getting past hard circumstances. I need someone who can take my audio, pictures and video and piece it together to create amazing finished products that are 30 sec to 30 min with most being 2 to 9 minutes. I want someone able to help me decide between choices sometimes. I want someone to do intro and extro for the videos. Some knowledge of what makes people want to watch and keep watching would be nice as well as knowing key words and other similar helpful skills.
