Good technique to find a GC for full rehab

[Maxwell Harrell]

Anyone have a good technique to find a good GC for full rehab when out of state?

We have a house under contract and need to find someone that can handle a full rehab of a large luxury SFR. We've asked our realtor who has experience with flips but he only gave us one. I'd like to build an applicant pool and interview to find the right fit. Any ideas on creative ways to get the right referrals? The assumption is Google isn't going to cut it.
