I recommend you go one of two directions here (or both).
1. Hire someone to follow you around filming who then edits the content down for different platforms and posts it with you reading and replying to the comments yourself. Don’t outsource that part. And you can interact with that person too without them being on camera. Ideally you want someone that’s smart, comfortable to hang around with, that will benefit from the association with you. If you can’t afford #2 below, then make researching strategies and tactics part of this persons job/internship.
2. Buy an hour of time from a consultant to brainstorm strategy. While there are a lot of traditional business SMM’s out there, there are also plenty of people that work with entertainers. Find them. Ask musicians that are achieving the results you seek for recommendations. Alternatively, you could just study other musician’s social accounts that are getting the kinds of results you’re looking for and try that out. If you get the right consultant, you’re far better off paying them a one-time fee than a monthly retainer for a SMM that’s going to post x number of times per week in x number of social channels. Something like that is fine for a guy that installs rain gutters or a restaurant but not for an entertainer. If you get good results with that person, you can come back for another strategy session when you’re ready.
I’ve run social campaigns for musicians remotely. While I can follow and connect with potential fans, peers, and influencers and keep a steady stream of content coming out but that is not nearly as effective as you actively interacting with both your followers and other entertainers and influencers.
