Need help finding a relaible/reasonable shipper

Happy New Year to all my fellow A'goners. I need to find a reliable shipping company to ship my Soliloquy 6.5s door to door residential. BAX claims they do not do residential. Only businesses. These speakers are monsters (59"x20"x15", 150 lbs. each boxed) and would prefer these be strapped down to a pallet for shipping. Any recommendations for a good, reasonably priced shipper to take these to California from Colorado?

Thanks,
Dma
