The LMB suppliers on my list that are close to you are:
Harbin Fish Farm
Culver's Fish Farm
Hartley Fish Farms (I don't know if they are still in business.)
Wallace Fish Farm
Moving to Oklahoma:
Moore's Fish Farm (east of Tulsa)
Dunn's
Plus others farther away.
I know nothing about the genetics/quality/service of any of the suppliers above.
Of course you always have Snipe (Kenny) at Aquatic Specialties as a valuable resource. He does not currently raise LMB. However, he may haul some LMB to eastern Kansas for a client at some future date. You might send him a PM with your contact info. If it ever works out that he is hauling less than a full load, it might help everyone to have him take a split load to your pond. (It never hurts to ask!)
Good luck turning your good bass pond into a great bass pond.
