You shouldn't be changing a binding contract. You should do what the contract says because you agreed to it.
I also have a contract dispute with my friend as his coffee making skills are not up to my expectations.
If you break a contract you should make sure you can afford the breakup clause. You could owe a lot of money so it might be worth finishing the job if you are near the end.
