How Much Does It Take to Create a Campaign?

I knew that it wasn't going to be like getting a proof from kt p print, where it might work out to a few dollars each. But i really think beyond any monetary thing, the time and energy a costs in olved with the campaign,. Like a recording my first audio book, which i honestly just finished yesterday, and i'm very happy with it. And then certain things that i had a lot of trouble getting fit into my schedule. Th those were the hardest parts.
