How to hire a 0 to 1 sales leader to create repeatability?

We are a pre-seed stage startup, about to raise our Seed, who's topline revenue numbers look deceivingly good because we have had a lot of founder led sales. We did hire one non-founder sales person, and one marketing person, but we know we need to hire a real leader to put in place a repeatable growth engine. No one on the team is really qualified to determine what traits we need for a 0 to 1, entrepreneurial salesperson. So I thought I would try asking here.

Some context, if it helps:

• We have about $170K ARR right now. That should get to about $270K if current contracts in diligence get through compliance
• We need to get $1.6M in ARR to raise our Series A
• Our outbound prospecting engine (a semi-automated "sequence" leveraging Apollo and Hubspot) doesn't work
• Our MQL engine is not yet effective, and has minimal budget behind it
• Our AVC is $10K
• We have been focused on one particular use case of the product, but the product is flexible enough already we could go after multiple customer vertical types, some of which have higher AVCs. If prospecting hasn't taken off in the ICP we have been focused on to-date, it suggests we shouldn't put all our eggs in that basket.
• We have some bigger contracts in the works that could really juice our topline numbers, but there would be a "vanity metrics" problem because we still haven't solved for top of funnel. We aren't having enough meetings. It is only a matter of time before that hurts us.
• We need a stronger velocity of ideation, and execution around top of funnel experimentation

We really aren't sure what traits we are looking for, or what evaluation / tests we could use during an interview to uncover whether those 0 to 1 traits are there. Would welcome any insight!

Thanks...
