As a guy who has built many H3 bumpers (over 100)...I think you should check your math. Usually, a price like that means one of two things: A crappy fab job...OR the guy is working for free. Hopefully its the latter! Two-hundred bucks would barely cover the steel and powder-coat, much less the welding, grinding, and head-scratching. Its the head-scratching that really matters. The amount of time you spend tweeking your bumper design will directly result in how well it looks, and works on the trail. I'm all about saving money, and $200 is certainly a great price...and I assume you are getting free labor. If so...take it! You're gonna make that fab guy eat that quote! I can tell you a few things to be aware of, before you even start...
Unless you want to chop-up the stock plastic fascia panel, you'll be forced to place the winch low between the frame rails, Defelice style. This will limit you to a winch with a small physical size....such as the Warn M8000 (that comes with the Defelice bumper). Some of the newer model 9500 winches might fit but, it will be tight for sure. Remember, you gotta put the control box somewhere as well. It would be a good idea to have a couple winches with you when you drop off the truck at the fab shop. Its tight enough under there, that you will need an actual winch to build from. You won't be able to build it Jeep style...and simply leave room for the winch. We're talking about fractions of an inch, and most likely...the make and model of winch you end up with, will be determined by its physical size (and not by what you want to use). BTW...an 8000lb winch is completely suitable for an H3. Given the location you're trying to use...you can't get winch-happy. Smaller is better.
If you don't mind cutting on that plastic fascia panel...you might be able to mount the winch ABOVE the frame rails. This would put your fairlead approximately where Recon's is, and also allow you to use larger winches. The protrusion of the winch motor will be the determining factor, and positioning it above the frame rails means the motor is free to grow outboard past the frame rail...something that can't happen if you're trying to keep everything confined in the bumper area. So, you need to decide early-on if cutting apart your fascia is an option. It will certainly open up more winch choices, and also make fabbing easier too.
