I would see if one of the local high end dealers offers to help deal with special needs if nothing else pans out. Or this idea resonates.
They are especially equipped to deal with delivery and unpacking of full systems. Once packed up, one or two of their guys drive a one way rental to your new home and contract with a local dealer to aid in redelivery. Fly the gentlemen home while you sit back in a fully set up room requiring only minor adjustments.
Air or ground domestic freight services usually get real careful with electronics at a certain dollar level plastered with tip and shock sensors. Can even gets ones that send a cell phone alert if triggered so you can start reaming someone out instantly. No idea what the risk level would be like if you are hoping to accomplish this near Christmas. I'd be very especially particular and adamant about consequences of diverting any portion off to a subcontractor. In writing, get every single movement and entity touching the pallets explicitly stated along with exact delivery instructions.
