I've been in the hauling/towing business for a bit over 10 yrs now, N-E-V-E-R pay upfront!! That is a sure way to start a whole boatload of problems. No reputable outfit will charge upfront.
Also, the hauling company should be able to provide you with insurance documents, showing type/amount of coverage. Usually this is no problem.... unless they refuse to show any proof and just say "yeah, we got that insurance stuff..."
About any towing company would be able to assist you in loading/unloading your rig from the trailer, we do several of these a week. Best of luck and enjoy your truck!
