I've seen SaaS companies pay 20-30% recurring lifetime commission for simply referring a paying customer.

If they are going to be attending trade shows, providing localized Clinical & Technical support it sounds almost too good. I'd be concerned that they have enough margin to actively promote and support your product.

I'd also want to set sales targets in any reseller agreement to give yourselves the ability to terminate weak performers.

Happy to jump on a call to discuss.
