I have a contract signed for129,760.00 I've received 2 of the scheduled 5 payments. The wrote me a termination letter and said my work thus far is satisfactory. My deadline was April 14. I believe they got a better price to finish the job. When I got this job last year they couldn't get anyone else. I could have had many other jobs but I dont overbook. Now I have no other work. I believe they are in breach of contract. Please advise.
