Need person to post 50 ads every 2 weeks on criagslist

I need a person with their own phone verified accounts that can post 50 ads every 2 weeks on criaglist for me. It will be under the service section for 2 different service businesses I do, and I have banner ads made up for each ad. It would be 2 ads a day for each business, and i want to pay every 2 weeks for 50 ads by paypal. Please tell me the cheapest price you can do everything yourself, your own accounts, everything a professional craigslist poster would have. Please tell me the cheapest price for 50 ads each time? This would be for an ongoing basis.
