Craigslist Long-term Posting in Housing Section Every Hour

I'm looking for someone who's reliable and very responsive to post ads on CL every hour in the "sublets/temp" & "apts for rent" sections in the housing category. Poster must be able to get the ads live and therefore it's better if you live in the US or have a DSL or dedicated line. I want someone who I can trust and work with long-term. I also want someone who would offer a trial first before I hire him. No crazy prices please. I've been here for a very long time and I know the prices.
