Canada>US Car Hauling Insurance

Any one here have a recommendation for car hauling insurance provider? 5 car enclosed wanting to haul between Canada and the US. 8 years experience hauling cars. No damage ever. No claims. Truck is 13 years old with 600,000km on it.
I have been quoted close to $50,000, of which 13,700 was just for a garage policy??
My broker tells me only Nordic will cover anyone for the US hauls.
Was I dreaming when I hoped to get a policy for closer to $20,000?

 

Thank you for your help!
Located in Alberta. I am 50 years old, fit, healthy, and experienced at this. No violations or claims.
Canada to US. It's the US travel that makes this expensive and complicated.

 

Thanks!
