Read your lease. What does it say about early termination?? That is what you can do. Anything else will cause a breach and will have the potential for costing you even bigger bucks.
Also, a warning... do NOT go to any of the 'lease transfer' dealers. They will take your money (and the 'new' lessee) and 'forget' to get permission from your leasing company. When they find out (or the payments stop) they will repo the car and you will still have to pay.
