Consider service providers which work in specific employee sub-segments. For example, create a relationship with service providers servicing the aboriginal segment. This is just an example, but you can work with service providers who hire people with certain disabilities, etc.. Service providers are always looking to staff at entry level positions.

Have you tried where job seekers spend their time?

Consider job boards like Monster, Glassdoor, Indeed, LinkedIn, Craigslist, or Zipecruiter.

Additionally, use sponsored Facebook ads targeted to your ideal applicant.

At first impression--because you need so many drivers--is I'd like to understand more about bus drivers, generally, and what their interests are. I'd also like to understand what other sorts of occupations translate well to driving, where some of your positive attributes can help someone consider a position or career change. Perhaps it's a higher hourly rate than what they're earning now, schedule flexibility, working with kids - whatever it is. Then put yourself where they are and get into their lives. Facebook is an obviously good place to start. Get yourself in the conversation and promote the good, interesting things about the opportunity you offer. If I was running this engagement, I'd map everything out and consider expanding the size of my funnel by asking questions about who we're looking for, where they spend their (virtual) time, and how to get in front of them. Happy to chat. PLS upvote if this was helpful.
