Wait what? Can thumbnail designing be a full time gig? Not for one but for 2-3 people?
Yes.
Imagine a content creator on YouTube or Instagram Reels who is going to get 100s of thousands of views through your thumbnails.
Potentially they are going to make quite a bit of money just from the ad revenue.
Now if you alone or maybe 2-3 people can come in and help them increase their click though rate on their videos by 2-3% that can make a difference of thousands of views and potentially hundreds to thousands of extra dollars just from the ad revenue alone.
Use Canva to do this, and you are on your way.
