Craigs list Poster Needed! Long Term! Experience A Must!

I am seeking an experienced Craigslist Poster to list approximately twenty predeveloped ads on a daily basis. Preferably, I would like to keep these ads in circulation and renewed on a daily basis. This would be ads that would need to be listed in approximately 6-8 major citys in the Midwest at a specific time each day. I will provide the list of citys as well as the ads. If I am able to find someone who can maintain twenty ads for at least thirty days within the circulation that I am seeking, I will move forward with listing more ads and will continue to do more. I am currently doing this work but it is time consuming. I would like to find someone who would do this at a flat rate on a monthly basis. Please send me your best offer and have an excellent day.
