WTD: Luggage transport from SF to BM, ~August 27-28

[random_vamp]

While my beetle can handle most of the gear needed for my GF and I, it can't also handle two bicycles and 9 days of water for two. I've got a rental van reserved if necessary, but would rather save the $$$ that it would cost if someone can give me a hand.

So, I'm looking for luggage space from the SF area to BRC for two bikes and water, preferably arriving on Saturday August 28th. I'm willing to pay a reasonable ammount for it as well, as it gets me out of renting a van...
