posting ads on craigslist

I am looking for someone that has experience posting ads on craigslist. Must be familiar with PVAs, flagging, gohsting, HTML. You must work with your own PVAs. You must gaurantee your work. Looking to post 35 ads per day for a week or so while I track the suucess. Then after getting the results of the tracking, I will increase the number of ads accordingly. Each ad will be posted several times a day, so you must be familiar with how to avoid the common problems that come with posting the same ad over and aver. Please respond with a bid amount or a cost per ad. Thank you.
