My question involves criminal law for the state of: California

I was pulled over friday evening, for tossing cigarette out the windows. I pulled into a gas station upon exiting my car I saw the police car. He told me what I did then asked if I had been drinking I told him the truth yes. Said he could smell the beer on my breath. The FST lasted about 30 minutes, which according to my account and my friend who was in the car with me I did not fail. I know officers look for tell tale signs etc, I know he was annoyed with me. Since when standing there, after telling me to keep my hands at my side I kept putting them in my pockets without thinking. Then when walking the line I just spun around rather then take small steps and turn around. All of these things I explained to the officer why I was doing them which annoyed him more. Then gave me the option he would judge me by my performance alone, I figured he would decided I was under the influence if I did not test, so really had no choice. I was so nervous and mouth was so dry it took numerous attempts to get a result. Which from what my friend was told a .082. I then opted for the blood test, and was booked taken to jail till 6am next day. I never want to go through this again.

I know I have to call DMV schedule the hearing etc. I know I will have to go to court. Most will suggest I hire a lawyer I am not rich, $4000-9000 is average I heard from them so far. I can not lose my license, I have to go to work. My financial funds are very tight, since I moved back in with my ex-wife to help support her and our child. Since she has been out of work for 6 months due to PTSD.

Heard suggestsions from friends etc start going to AA right away, even start the DUI program. They are not lawyers or even know the law though.

What are my best options here?
