Drive Traffic to My Website Via Craigslist, BackPage, SEO, or Other Methods

I have some Craigslist ads that I would like posted in all major cities on the Craigslist website. According to their Terms of Service, one must post the ad manually. to direct visitors to one of my websites. If you would like to use BackPage, other classified ads sites, social media, or SEO, please respond with your proposal. My top budget for this is $30 per month. Please describe your action plan. I will try for one month, and if the ad campaign is successful, prolong the arrangement into a full-time gig. I can show you the site in a private message.
