Craigslist Marketing Campaign

Hi, I was wondering if someone could do a recurring project for me. I need 25 - 40 ads posted every month on Craigslist. They would each need to be in a different city within the US. This is for my tutoring business and it would need to be placed in the Services-> Lessons category. Please let me know if you can do this and how much it would cost for you to take this on. If you could also alter the ads slightly every month so that it doesn't get taken down, that would be greatly appreciated (and if this requires additional compensation, please let me know how much).
