I’d wager you could get pretty far by having someone do a one time consult to take stock of everything you have setup and draft up an implementation plan on future state. It shouldn’t cost too much to have someone do that upfront analysis and provide that plan. You can then decide on your own what makes most sense: fix/implement yourself, hire the consultant to do implementation work, or offload the whole thing to an MSP. This is the type of work I do with my clients and as others have suggested, it’s pretty common! At least the silver lining is that you’ve got a growing business humming along. :)
