Wedding Flowers Problem: where do you store 800 roses for two days before the wedding?

I'm doing the flowers myself for my wedding and I've got them coming in from a wholesaler my aunt hooked me up with (her husband owns a greenery), and I'm ordering about 800 of them. I have no idea what size packaging they will be in, but I do know they come in sets of 100, and those are packaged individually, so there will be 8 boxes/buckets/whatever. Where the heck am I going to keep all these flowers? You're supposed to refridgerate them. I can fit two in my fridge I think, but after that, what to do? I thought about getting a freezer chest and not turning it on, just putting fresh ice in every once and a while, but they are really expensive. Any thoughts on how to do this in a way that doesn't break the bank (the flowers are already expensive enough). Thanks!
