Mom died on 7/3/13, she didn't sign her will; need to terminate the guardianship/867 trust ASAP. I don't trust my attorney. Guidance?

My dad's will was probated in 2011. I am trying to find an original with a signature on my mom's will. I'm waiting for death certificates from the funeral home. My current attorney really wants to probate her will, but I don't trust her. (I didn't tell her it wasn't signed.) She already informed me it would cost $3000 to perform work on some issues I had with the hospital and a state agency. She didn't even want to discuss a plan of action or a timeline to address the issues, or schedule a time to meet in her office. I'm not an ATM, and I don't conduct business like that. I'm afraid to talk to the court about retaining another attorney because they act very suspicious and may not grant the request. I don't want to be stuck with the current attorney.
