Craigslist posting

I want to post advertising a job in various towns and cities on Craigslist. My project is a network of local event calendars. I am attempting to start these local event calendars in multiple towns around the world. I want to advertise for people (one in each town or city-neighborhood) to upload events to my platform to create a calendar in their town or city-neighborhood. I have already posted to multiple towns and cities on Craigslist, but i am tired of getting ghosted and my helpers getting ghosted. I see that some postings are in multiple towns in certain categories of Craigslist. I need professional help to achieve that result. I am getting good results from my Craigslist posts. Still I would like to start with you in a small way, just in the USA, to see if this service works. If it does I will expand from the USA to the world. Thank you. David
