How can I terminate a managerial contract? (Entertainment related)

First, check your contract to see what it provides for termination. Often managemen contracts provide that unless the manager's efforts get you a minimum income within a set time frame, you can terminate the contract. Your contract may have other provisions this manager has not met, such as the obligation to finance things such as headshots. Next, if you do have grounds to terminate, check the contract to see what you hagve to do to terminate. You probably will have to give written notice. Whether your contract says so or not, you should give notice of termination by a provable method of transmission, like Fed-Ex or personal messenger, so you can prove when you gave notice.

Also, in California, managers are forbidden by the Talent Agency Act from performing certain activities that agents have a monopoly on, such as booking shows and obtaining publishing deals. If your jurisdiction has a similar law, and your contract provides that the manager's obligations include some of these activities, you may be able to file a petition with the Labor Commissioner or similar authority to terminate your contract.
