I have used Commander and Company (Terry Commander) and they operate and are licensed in 521. If she is in the part of 521 that you are hunting, I would highly recommend her and her staff. She is on the list that you were looking at. Good luck with your hunt.
Here is an inexpenive and effective deer feeder I made recently.
No batteries to go dead, no hoisting it up in the tree, plenty of capacity, very easy to fill - so far, I love it.
I have made two of these and they are easy to build.
An empty 55 gallon drum, some 2x4's, some PVC tubing and fittings, a little bit of hardware and some paint - and you are ready to go.
I designed it so you can stand on the lower rung and fill it - the top is about 6.5 feet above the ground.
It holds about 375...
