I did talk a bit to one of the reps at a custom T place. I am thinking of going with a long sleeve, and there are options. Personally, I am leaning towards a performance long sleeve, UPF 50 type deal. A good shirt to wear in the summer while fishing.
I'd put the Rileys logo on it, and an Ozark Anglers logo. Something Like "Ozark Anglers - Jigfest XII" on the back. Have text like "Buffalo City" on one sleeve and "Arkansas" on the other.
Probably going to run around $25-$30 per shirt. Depends on volume, we would need at least 10. There are less expensive options if using cotton for the shirt.
Something high viz too, so you can spot the other guys even if they are 3 miles up the river.
