Reschke,
I'll try to help if I can.
First, what you describe is called many things, usually a "preserve shoot", "controlled shooting area" or (out here anyway) a "put 'n take".
Shooting pen raised pheasants depends a lot on the pen. If you have the most economical, basic "containment" type pens, then when you put the birds out it will be similar to pen raised quail. That is, they pretty much stay where put and flush when pressed (sometimes with a necessary boot) and they fly very poorly.
If you have good pens, say 200 yards long with 20' height or better, and they are scared and flushed regularly in the pens by humans, you can get a better product.
Now, all that aside, I've never seen, shot or eaten a pen raised bird that can compare with a wild one. Wild ones are tough quarry. They've spent their whole life avoiding predators...hawks, coyotes, bobcats... and when hunting season comes, humans. They are hard flushing, fast flying, evasive, hard to kill (a single bb will often stun a pen raised bird to the point of landing and waiting; this rarely happens with a wild bird. They'll carry more shot than you can imagine if you don't hit them right.)
So, all that said, I occasionally use "put 'n take" places for training young dogs before season. Usually the preserves operate from August to April while the season is November thru January.
To me, this is the most correct use of preserves. I don't see them as "real" pheasant hunting. This isn't to be snobbish, it's just that there is a vast difference in the experience due to the difference in the very nature of the quarry.
If you want the real flavor of it, get 2 good buddies and plan a trip to the Midwest and hunt wild birds.
There's tons of public hunting out here in all the states. There's open Federal and State land (usually around lakes so you can get in some duck/goose hunting too), there's State sponsored "Walk-In" hunting land where the State leases hunting rights for the season from farmers. Yes, this type land gets more pressure but early in the season it's good. You can often get permission for private land too. Opening weekend is usually reserved for "family hunts" with siblings returning from all over the country. Same for the time around Thanksgiving. Usually after Thanksgiving a lot of private land opens up.
People out here are pretty friendly. You'll meet some that have a hard-on for hunters, usually folks that have had disrespectful people damage property, leave gates open, seen hunters acting like jerkoffs in the cafes, etc.
But mostly, if you're friendly and polite you'll receive the same treatment in return.
As to sites, here are a few "how to" sites:
Pheasant hunting tips (Note that different states have different regs for shooting times, etc. Also, I disagree that 2-3 men can't hunt standing corn; you can and successfully. There's ways and there's ways.

)
More Tips Stick with a 12 ga., even on opening day. Shoot for the white ring on the neck, not the whole bird. 6's are fine for opening weekend, switch to 5's or 4's for later season birds.
Bunch of good links here, mostly stories, didn't read them all though.

I have several friends that come up from Georgia every year.
Here's a few observations.
If you have a good quail dog... one that can be kept close like a Brittany, not an English pointer... bring it. If you have a far ranging dog that you can't control, leave it home. Believe me, you'll enjoy the hunt more without a dog than with one that's busting birds out 250 yards in front of you. It's not the dog's fault really and you're going to get angry at it despite that.
Bring clothes suitable for steady walking at temperatures from 85 degrees to -10.

Bring your best walking boots, Gore-tex if possible. Conditions change in a blink out here. There's an old saying... "If you don't like the weather, wait 15 minutes." If a "norther" blows in, you can start hunting in a T-shirt in the morning and you'll be wearing everything you own by 2 PM.
Most Southern guys generally overdress. They bring their "sitting in a deer stand" insulated coveralls. Walk for about 4 hours steady in those and you'll know why it's best to have a good "layered" system consisting of light, moisture wicking stuff.
Guns: Any 12 ga, most guys should be choked modified, use 2 3/4 1 1/14 HIGH SPEED (1300 FPS or preferably the 1400 FPS) 5's or 6's for early season. High velocity puts them down. PERIOD. I've done some pretty definitive experiments over the years using different brands and different velocities within the same brand. What matters is VELOCITY; that's what keeps the crips from running when they hit.
Trucks. Any vehicle with decent ground clearance, good tires and lots of room. I usually get myself in 4WD situations a couple of times a year but most can be avoided if you pay attention. So 4WD is nice but not necessary really.
I'd be happy to help you in any way I can.
