My discipline is design, and I have limited experience hiring marketing consultants. Lately, however, as I try to help clients gain maximum exposure for themselves, I have been recommending that they retain a social media marketing person, to make sure that they get the best results from the designs that I do for them. I have seen prices all over the place. Whether it is for building a Facebook campaign, or any other elements of developing strategy and imlementing it, I have no idea of what is reasonable. Can anyone offer some suggestions for gauging what really makes snese?
