My question involves restraining orders in the State of: Ohio

How do I appeal a Domestic Violence Case against me where Judge denied my evidences video, audio, stated no "Foundation", which showing that the Petitioner was the abuser who was beating me on the video. On the audio she was asking me for money and scary with me with a knife for not giving her any money.

Judge said that he found no evidence that the Petitioner was motivated by money. And, he found me unreliable.

I have talked to lawyers but asking me lot of money. In a price of $1500.00, what would a retainer feel like? How much I would expect to pay a lawyer hourly to appear Domestic Violence case?

Some lawyers ask to be paid in full amount in. Some ask to pay half. Some ask to pay hourly and with a retainer fees. Which one best.
