After viewing some of your videos, I believe that I could greatly increase the production value of your content. I would be able to chroma key your green screen better, perhaps color grade your footage, add background graphics, and mix/de-noise your audio. I have a lot of experience with Premiere Pro and After Effects, and would be able to edit and send you back your videos within, at most, a week, and more commonly within 3-5 days (Provided that videos are sent every other week). It may also be of note that I am a native English speaker/writer.
I am also noticing a couple of visual issues with your videos, such as random scaling changes, and cropping errors. Your green screen is also somewhat visible, and I could fix these issues entirely if you were to hire me. I also know what makes thumbnails attract viewers, and how to make them appealing. I may also be able to add subtitles, and can absolutely do video tags. If you do hire me, we can work out details, etc. Thank you for your consideration.
