Social media Manager

So, I’m making a small business about graphic design rn and it needs one or more client managers. Their jobs will be to find, message and talk to clients. The pay will be 10-20% of of the revenue their clients bring in. The project hasn’t started yet, we are hiring people at the moment. Just to clarify, I’m in middle school right now and no one is serious at my age. I am not exactly looking for an employe, rather a freelancer that works for our business Draftify.
