Reignman,
Just ask for a public defender. You'll have to fill out a one-page financial application - if it shows you are low-income (or have many dependents), then the PD will be appointed on the case.
You are usually asked if you have an atty before you plead. If they ask you how you plead, ask for the PD. You will need to plead 'not guilty' in order for your atty to negotiate a plea bargain (once you say 'guilty', it's over - there's nothing to negotiate - the Judge will just sentence you.
DO NOT plead Guilty.
Your case may be triable. If the other party was combative, then it may be mutual combat & a jury may return a verdict of Not Guilty. Also, the Prosecutor MAY decide not to charge, or to send it to an 'office hearing'.
You'll only know, on 8/25, what your options are.
My best advice - do not plead guilty. Take it to trial. (Trial would be set at a later date ... latest 45 days)
Do NOT make any comments on the facts of your case to the Judge or the Prosecutor. Tell the PD all the facts & let him/her guide you.
If the Prosecutor talks to you before a PD is appointed, be respectful (that's the person who can reduce/dismiss the charges), but DO NOT admit guilt and DO NOT speak of the facts - they may have to testify against you & your statements may be taken out of context. It's fine to tell them that you've never been in trouble before & this situation has made you sick at heart and you want to resolve it & you have a spotless record and you're sick at the idea of having your future ruined over this ---and what will happen, now ? Can you do community service to dismiss it ? but - DO NOT admit you are guilty & do NOT speak about the facts of the case (who started the mess, etc).
If you ask for a trial, the other party ('victim') may not show up - by then, he's calmed down & doesn't want the bother. You may have to take it to trial.
Good luck.
