Buyback Guarantee and Hiring More Inspectors

I try searching and could not find any information on this matter. I am subcontracting work out to an InterNACHI member in my area through my company.

My question is really for clarification about the Buyback certificate. It be my inspector information on the certificate since my company buys the policy and would be the umbrella coverage for my subcontractors correct? And does the subcontractor also have to participate in the program?
