Craigslist posting service about 60-80 ads / month - repost

have a few ads I want rotated and posted on craigslist. Looking for only 2-4 ads / day for a cleaning service in Detroit area. All ads will be under service section. This job will last for 30 days so we expect about 60-80 ads for the month. If all goes well services will be continued on a monthly basis, and if business picks up we will expand marketing to other cities and double the ads posted. I have found companies selling bulk craigslist ad posting but most have a 25 ad / day min so I'm on here looking for smaller packages. MUST BE POSTED DURING DAY FOR EASTERN TIMEZONE AND SPREAD OUT THROUGHOUT DAY - I don't want everything listed at 2am all at once etc
