Easy answer, avoid hiring a sale staff, because you'll have to manage them + pay them, which will quickly suck all the hours out of your day.

Better to just speak at Meetup groups + conferences matching your target client avatar.

Conferences that come to mind are Affiliate Summit + PubCon.

There are 1000s of other conferences.

Fill out a free speaker proposal as the first step. This will allow you to hone your sales pitch to a perfect state.

You'll know your sales pitch is good, when conference attendees start voting wildly for you to speak at conferences.

This is a great way to reach 1000s/conference of qualified leads.
