Craigslist 50 postings in for sale, multiple cities

I am looking for a good offer to have ongoing ad placement on craigslist 50 ads at the time every two days in sales section of the craigslist, multiple cities across the US. People with their own PVA's and some ad design preferred but English speakers with experience with craigslist postings welcome. You are bidding on 50 ad placement, the order will be repeated every two days for as long it is beneficial for both of us. Cheers
