Fisheye47, you don't really need an outfitter to have a good hunt for Sikas in MD. Blackwater Wildlife Refuge is 13,000 acres all units combined and has a good pop. of deer.
Thers also Asseteage Island which is good to. Both are public access, Blackewater has a $20.00 archery permit. Assateage has a $70.00 vehicle access permit fee but is not required if u walk in. (Not recomended).
Haven't heard to much about Muddy Marsh but I believe they hunt over bait, which is not my bag, nor do I believe it helps, just turns them more nocturnal.
You can write to Blackwater for info:

Hope this helps
