I have about a dozen or so DWFs not yet picked up in the Entree Forest (and amazingly, there are no duplicate species among those, my friend last nite being a female Emolga). I have four Dream Balled in the W2 PC now, a batch from trades already in Black, and a bunch from Dream Radar that are sitting in W2, and my machine claiming I'm out of energy even though I never changed systems with the game (!).
I have to keep 13 boxes untouched in Black since they are my entire Pokédex from 1 to 649. That gives me eleven boxes to work with.
Box 14 (might be 15, not sure if I use 14 boxes on the Dex) currently holds a bunch of randoms that I can give away or just say goodbye to; I'd rather give them away. Box 24 is my Trades box. Boxes 22-23 are a copy of every single legendary from my Dex (I can relocate these, perhaps, but this is a long task without the multi-move option in B2/W2). Boxes 18-21 all have babies in them. I have a group of copies of the seven Fossil Pokémon and some copies of legendaries in 16, and 17 holds a lot of other Shinies and legendary copies. There's other stuff I'm forgetting in the one or two unmentioned boxes. That PC is practically out of room!
This is why I have to get all of my babies moved over to W2 as soon as I can (and my legendaries over to Black as well), but since three of those four boxes are completely full, it makes it even more challenging as I have over 100 individual trades to do. It will be a long time before I'm fully ready to operate a shop (which might be why I've been procrastinating, I have to find a job as well). Running a breeding shop with my Pokédex is easy, but throw in DWF and it'll be a challenge finding space for everything.
Since your shop will include all your Events, I can easily check your list for any I have that you don't. I obviously won't need every single Event myself (and don't really need that many, I never saw a reason for keeping 14 different Victini or Rayquaza or such just because different Trainers want different natures, they tend to be happy with whatever they can get most of the time from my experience, especially if the IVs are high). My Events tend to be in one or two boxes, and I think you already have my Flying Pikachu as well, which is the one I was really looking for (I sure hope that can go to X/Y someday). :)
So yeah; my main breeding shop is ready, but the DWF portion is far from complete.
