Finding Business Consultants to Unlock New Opportunities

Hey everyone, At my org we’ve had some success with working with business consultants in our space introducing us to people that can yield us some pretty big deals. That got us thinking that we should be trying to find more of these consultants to see what are actual greenfield is. Problem is that the ones that we’ve worked with have come directly from our network. So that got me wondering if anyone here has done something similar in the past and wanted to pick your brains if so.
