Talk to your local high school, tertiary college or university to see if they need businesses to work with for case studies, IT development, marketing planning or other areas from which your business could benefit. Being a business case-study partner for students as they work on a project could bring valuable fresh ideas through which you can grow your business.
Offering structured work experience with a local high school (not just for free lab out) is also a great way to find smart workers and build connections with a local organisation with dozens of staff and hundreds of parents.
