If not, what is the best method you would suggest to reach decision makers at scale? I would like to get their attention and generate interest in the offering.
It's really simple arithmetic. If you pay your sellers to close deals and they make, say $200k, why would you want them to spend time doing what you can hire someone for $60k to do?
I've used the outside "appointment setter" companies. They usually charge roughly $700 per appointment. So, do the arithmetic again. If you close one in, say four, then add $2800 into your cost of sales and see if it makes sense.
