Hello, my name is Zane Rankin and I can for sure help you with all of the tasks you are requesting. I would be willing to create thumbnails for a certain amount of videos (we can determine how many, I can send you examples of my previous thumbnails) along with linking paypals, watermarking the videos, helping you secure your account, adding social media, creating a organized and attractive channel, and more! I would love to work for you!
