Southern AZ Sandhill Crane Guide Recommendations

A family member drew the Sandhill Crane hunt in southern AZ this year.  They’ve tried calling one of the popular guides down there without success. Wondering if anyone has used a guide and what there experience was like?

As an aside, I did this hunt myself a couple of years ago and only had a day to hunt. We set up on a pivot on a field that we had permission to hunt.  Got all set up with decoys before first light.  Right when birds started to fly a big group of other hunters drove up and started setting up on the edge of the field that we were on.  Felt like they kind of messed us up and we never got any birds.  Would love to go out and give it a better effort next time!
