Can I file this motion myself, or would it be expensive to get maybe a young PD just to help with the paperwork?

I was accused by my ex-wife of pushing her domestic battery. My paid attorney did not turn in any of my evidence or witness subpoenas by the discovery deadline date. But the day before the deadline we texted and I asked him if he had everything in line and he said he did. He lied to me. He was always late or unprepared to every pre-trial conference. My daughter has witnessed her mother inflict self-harm and tell police that I did it. I gave him everything to prove my innocence and he was too lazy or overbooked to do his job. So yesterday I lost a bench trial and was sentenced to probation.
