Craigslist Posting Ad

We need to have 100 craigslist ads posted in the free section for job hires... We have the wording of the ad and just need someone to post those for us, in the top 100 markets in the US. This needs to be done within a 3 day period of time or 1 day is preferred since we are looking to hire many writers for our business. Is this something you would be interested in doing? Please advise asap
