I've never heard of anyone offering this kind of service here on Hive, so it feels unique to me, but it's certainly viable. A good reason for its potential success is the upvote support you're offering as a "bonus" or like a "cashback reward."
I'd like to see this approach applied to other types of services or crafts too, e.g., coding, artwork, writing, or other skills.
After all, Hive is "SocialFi" - a mix of social and finance - and what you're offering could help create a circular economy here.
Thank you for this valuable feedback :)
