Rev-share sales partners for SaaS. as anyone made this work?

We have multiple SaaS products. Products and delivery are solid, but I'm wondering if hiring full-time AEs is premature.

My idea: offer independent sales operators 20% recurring rev share for the lifetime of each account instead of a salary. But I keep hearing that good closers won't touch commission-only deals.

For those who've done this where did you find these people? What's your experience?

Agency/reseller partners instead of individuals?
LinkedIn outreach?
And what terms actually made someone to commit to this?

Would love to hear what worked (or spectacularly didn't).
