We did it in June

Buy a 12 foot trailer and bring your stuff down yourself. We drove it easily in 4 nights, 5 days from just north of LA, could have done it faster if necessary.

You need to re evaluate what you are bringing down. Forget the TV's, mattresses, that kind of thing and buy them here. Except for items with sentimental value or artistic or in our case, our kitchen stuff, you can replace it all for less than it will cost you to bring it down.
