Can't give you a cost, but you won't notice any problem driving it for months. I don't mean drive it for months like that. I mean no problem is likely to show up for months. The dealer has repair kits with a new boot and the proper amount of grease. As a steering, suspension, and alignment specialist at a very nice Chrysler dealership for nine years, I never saw a cv joint on a full size truck up to 1999. Dakotas used them but I never needed to replace a boot on one of them. The boot kit for a Caravan runs around $30.00. It's about half that from the auto parts stores. Those take about an hour to replace. All of the trucks I worked on had regular universal joints.
You should have the boot replaced as soon as possible to keep water, road salt, and dirt out. The roller balls and grooves they ride in are machined to very tight tolerances to make them quiet. Dirt is the enemy.
