Yes, we outsource our social marketing, to improve our brand awareness. The companies we use actually interact with you and do what you want, not some made up plan.
Are you after a Professional Social Media Manager?
Or just somebody to set up the accounts make a few posts and buy a few fake likes/followers?
Is this for your business or a clients?
A good SMM Manager won't be cheap but as with everything, you get what you pay for.
