Would I be able to keep my license on my own or would it be best to spend the money on an attorney?

I got pulled over for not completely stopping as he put it. I didn't S.T.O.P stop by which he means counting to 4 in my head. Now mind you this stop sign, I supposedly rolled was on the other side of a hill and in no way visible to the cop. He was going back and forth between two bars in our small town. He gave me my field sobriety test after which he told me I could go put on my shoes that it was most likely going to be a warning for the stop sign. At this point, he gets out the breathalyzer and arrests me. Now obviously I blow again at the jail and blow a .082. I had two beers with a pizza over I’d say about 45 minutes). Does it have any weight that he then wrote on my ticket that I was obviously impaired (after stating that it was just going to be a warning) and that he was training an intern? I am a single mother and a full time worker and student. I have met with one but I didn't like him though he did offer to do it for 15 instead of 25.
