Craigslist postings

I need someone that can post 30-50 ads on Craigslist a day. I know how to use craigslist but what I don't know if how to post ads the same ad (changed a little) in different cities and have them get excepted and not taken down. So I need someone who really knows craigslist inside and out. This might be an ongoing project as long as it is working and the posts are staying up. Please do not bid if you are not a craigslist expert. I can not teach you how to do this. You bid is for 30-50 ads for 7 days straight. I will evaluate your work and how the ad is doing after that to see if we keep going.
