I want to know what to do?

My husband recorded a cd with j&nv publishing and he signed a contract with this company. They didn't do anything that the contract said. They where suppose to pay him 7000.00 for the first recording they only gave him 4000.00 and never called him again. Its a long story can someone call me so I could explain better? But I need to find a lawyer and maybe someone could help me with that 646-399-2057. My name is Olga Rosario
