I agree with Greg – great job on picking a specific sector to go after.
I do think that the economic recovery may be uneven either in geographies or industries in NZ. It may make sense to start your focus in those geographies or industries that are seeing pick up. You can always do broader marketing but focus can help make sure that your time spent yields the highest return.
I also wonder if you can spend some of your time forming partnerships (this may have been your reference to channel partners) with accountancy firms, legal organisations, etc. as a way to generate leads more efficiently. Most likely during this time people will be talking to these types of firms to understand cash flow, etc. .
Finally, another idea is to hold some free seminars (or create online content that family businesses could use to plan) about family run businesses in our current economic climate. Maybe smaller roundtables with key owners that you know plus others that you invite to discuss how they are approaching the current situation? It may allow some high touch, trust building opportunities to generate business and consultancy.
