Drink driving advice needed

Hi,
I was stopped by police last night and was asked to blow, then the police brought me to police station to make another blow.
It was 0.104 grams. This morning I checked the internet 0.104 is quite high offender and might get my license suspended.
This is my first offence.
Please advise what I should do, I need my license to work and for sending kids to school everyday.
Do I need lawyer or just plea guilty? Normally how much the lawyer charge for this case?
Can anyone recommend good and affordable lawyer in Perth?
Thanks.
