I'm the best candidate for this job because I am highly specialized in digital advertising with over 10 years experience managing some of the biggest brands in the world. While working at ad agencies, I have managed 2 million dollar++ per month budgets for brands such as Comcast, Home Depot, US Department of Veteran Affairs, Georgia Pacific, BAE, and more.
I believe in transparency and simple billing. My standard rate is simple, $150 per month per campaign. For instance if you have an AdWords campaign and a Facebook campaign my rate is $300/mo. However this is negotiable depending on the number of campaigns you are running. The rate includes daily account management, ongoing optimizations, and monthly reporting.
Please tell me more about this project so I can let you know how I can help. Every project is different and small goals can completely shift the strategy. What do you want for proof of low CPC? What do you consider a low CPC? Depending on keyword competition and landing page relevancy average CPC's vary greatly. I have the skills and active campaigns to prove it, just not sure what you would like to see as proof.
