First Time Offender, Retail Fraud 3rd Degree

Hello,
I was recently charged with retail fraud for allegedly trying to steal $56 dollars worth of goods from a local department store in Michigan. I was taken in by loss prevention, and my information was taken down, a report was written up by them, and an officer came and took to the the police station where I was booked and held on $100 bond. I'm currently waiting on my arraignment and I'm wondering what I do now.
I'm a 19 year old male and a first time offender with no prior criminal record. I'm looking to get this over with quickly and cleanly. I feel a diversion program would be ideal, if at all possible to obtain, as I don't want even this misdemeanor on my record. I will be able to pay the fines, and civil damages provided they are under 1,000 dollars as I don't have much money floating around. I'm not familiar with the criminal court process. I would appreciate any incite into this process, and in your opinion what I might be facing in terms of punishment? Should I spend the money I have on a private lawyer, or go with a Public Defender, considering even my best case plea deal still probably has me facing several hundreds in fines?

I don't want even this misdemeanor on my record.

The time to think about that was before you "allegedly" stole, not after.

Not much I can do about the past. Just trying to make the best out of my mistake.
