429083 I need an ad poster for me

I need an ad poster that will post on backpage, kijiji, oodle, classifiedads, and several other sites I will give to you, nothing as hard as craigslist to post on. It is for plumbing ads. How cheap can you do 1 ad on 10 different sites, every day for a week. I will pay week by week. This is for 70 ads a week approximately. The same ad you can paste over and over also. Tell me how much you can do 70 ads a week for?
