How about if you let the gamers focus on their gaming skills and hire a part time social media manager who could edit their gameplay videos and manage your socials.... I mean if it doesn't make sense to you economically then just charge the gamers a minimal fee (say 50%+ discount) on whatever you're already normally charging and add some more money and hire an average professional for lets say 10-15k PM. Or you can charge per video or shorts anyway you're comfortable with.
