Craigslist manual ad posting required

We post 1 ad in 30 cities per day on Craigslist in the USA. We need someone to do this for us. We prefer manual entry, not automated, to ensure the ads are posted. You are responsible to keep up to date with any techniques to make sure the ads get posted. If you are located outside of the USA, you must ensure that you can post to the USA Craigslist site and be aware of all other current CL limitations. Please advise us your cost and details for this service. You may assume 1 ad in 30 cities per day, posted at approximately 8:00am EST (New York time). This is slightly flexible if necessary. There is also potential to increase to 2 postings per day (1 ad, 30 cities, posted in morning and evening, for a total of 60 postings). Please advise the cost. Our target is less than $0.05 US dollars per posting. The lower the better, but quality must be good too.
