Craigslist/Classified posting expert

I am looking for Craigslist posting service for the job section. I have several job boards and looking for bilingual job seekers. I would like 10 ads per day one ad in 10 different cities and job categories - 70 Ads/week I want a posting company to post without getting ghosted. Please respond with your quote for monthly cost. Would be great if you are also an expert in other boards such a Kijiji, backpage. You should be experienced with this and already have done this before in the job section so you can advise me on the best method. I would like a day or two for trial
