I have mounds of experience posting to classified ad sites, especially Craigslist. I also have a relatively low flag and ghost rate due to my methods.
As long as you are providing me the ads, as well as 50% on Sunday and 50% Saturday, and all my job is is to post them, I can help you out for $800 per 1200\7 days.
I have my own posting solutions, and can start work within 48 hours. If this is more complex than what I'm interpreting it as, please PM me so I can give a more accurate quote.
Thanks!
