It depends on how many "battles" you want your attorney to "fight" and the difficulties of each "battle." If, for instance, you want representation only at your arraignment, the cost should be fairly cheap. It will cost a lot more if you want him to challenge evidence, file motions or take the case to trial. Many attorneys also charge extra for fighting the automatic driver's license suspension by the DMV. It also depends on your history. It will probably cost less if this is your first offense than if you have previous DUI convictions. And it depends on the facts. The stronger the DA's evidence against you, the more it will cost to fight.
In your case you said you had one drink but the officer said you were "drunk." If your blood did not test at an alcohol concentration of at least .08, then you cannot be charged with the "B count" in which impairment of your judgment is presumed. But, you can still be convicted of the "A count" if the prosecution can prove you were impaired by putting on additional evidence. (e.g. erratic driving, speeding, stumbling, slurred speech, "failing" field sobriety "tests",etc.)
You should consult an attorney in your area who can give you advice tailored to your specific situation.
