Craigslist Posting Project 1 post per city, May need to generate Ad variation. Project will repeat every 2 weeks to 1 month. - repost

We are looking for safe and efficient way to post 1 post on every Craigslist cities per week. We also like the listing to drive traffic to our website if possible. Must have prior project experience and be able to present it with links. The bid is base on PER week frequency, and final links must be provided for verifications. So if your bid amount is $200 that means you would charge us $200 per week to post 1 listing on every Craigslist city in United States and Canada with links to prove your work. Since we only have 1 ad template and not hundreds of unique ads for each city, we would like the bidder to provide a solution to either allow that to happen or allow us to generate random unique posts. Please discuss you will accomplish this when bidding for this project, if we don't see you addressing this issue we would assume you haven't read the post in it's entirety and will effect how we select the bidder. Finally we will spot verify the post, we need the post to stay so please have experience with craigslist to ensure the post stays. The post will be simple text with URL links.
