What is this going to cost you ask? You had to ask or you wouldn't be on this page. The short answer is good advertising is free. Only bad advertising is expensive. Great advertising pays for itself ten times over where bad advertising is pouring your money down a hole. If you don't advertise, nothing happens. Nothing is a bad thing. Bad creative is very expensive.
If you're serious we have our SAMPLER MENU for those uninitiated to great creative.
