I have so many questions but going to have to make some assumptions...
If you can afford hundreds of statues but you're complaining about $300 a month, it sounds like you are probably more comfortable with capital expenses than operational expenses... so... would recommend:
1) Assess your statue collection and see if there are any you are willing to say farewell to. You probably won't make a profit from it, but perhaps someone else who can't afford hundreds of statues can enjoy it.
2) If you decided to part with any statues from step 1, then pack those in a box and put them up for sale
3) For all the rest of the boxes, get rid of them all! (please recycle) If you really want to keep some, limit it to your top 10 most expensive/complex statues
4) When the time comes to move the statues, go to a commercial supplier and buy a significant amount of styrofoam and custom foam cushioning (they are pre-cut in tiny cubes). Will probably cost $1-2k for your statue count.
5) Pack your statues:
5.A) Can do it yourself...
5.B) Call one of the statue companies to come over and help you. I've heard of a few people doing this with really expensive collectibles ($10k+ range)
5.C) Call one of the really high end movers who have experience, insurance and certifications to move high end items to help you (usually from around Beverly Hills or Malibu)
6) After you move, sell as much of the styrofoam and cushioning as you can, perhaps mark it down a bit and do this around the time of Aug/Sept when people are moving to school so you get some of your money back
7) Enjoy a new layout of your statues and clean space
