You’re undercharging, but that could be part of the problem. Unfortunately the clients with the lowest budgets often have the highest expectations, and while I understand SMM is a large investment, even in these ranges, there are clients out there who would pay the worth and let you do your thing. They are saving $ on hiring an employee, doing the work themselves, training and health insurance. That’s a LOT of deliverables and if you broke it down you’re not compensating yourself.
