USA Storage Facilities That Will Accept Car Parts and Store Them for You

Hi, anyone know of any USA storage facilities ie: garage size, that will accept goods and store them for you?

Basically gathering car parts of eBay and Craigslist etc and wanting to get them shipped to California and put in storage until I get a container full.

Then I'll fly over and load the container and get it shipped or better still if the storage place can do that for me.

Thanks.
