If you're in Kittitas County and it were me, unless I were convinced that the lawyer was actually going to get a better deal such as an outright dismissal, I would see if I could get the deferral described in those guidelines before paying a lawyer.
Some of the abbreviations in that document are not standard.

Loaded Rifle or Shotgun in Vehicle - 77.15.460
If no prior DFW violations (of any type), 6 month SOP (RCO probation with 1 $100 record check) with 24 hours community service within 90 days to a dismissal . If prior DFW violation (s) , 364/361 with a reporting date 90 days out and 12 months active probation. The three days jail may be met with proof of 24 hours of community service within 90 days. If more than one prior, additional jail.
Based on the context, my interpretation is:
If no prior [Department of [Fish & Wildlife violations] (of any type), 6 month [Suspension of Penalty] ([Record Check-Only] probation with 1 $100 record check) with 24 hours community service within 90 days to a dismissal . If prior [Department of [Fish & Wildlife violations] violation (s) , [364 days in jail with 361 days suspended] with a reporting date 90 days out and 12 months active probation. The three days jail may be met with proof of 24 hours of community service within 90 days. If more than one prior, additional jail.
Under my interpretation, a first offender under the guidelines would receive a six month suspended sentence (paying a $100 record check fee to verify eligibility, and also paying other court assessments), and would have the option of completing 24 hours of court-approved community service within the first 90 days of the sentence. After six months of unsupervised probation the court will hold a hearing to verify compliance with probation and, if the defendant submits acceptable proof of timely completion of the community service requirement, will dismiss the charge. If no such evidence is presented but the defendant has otherwise complied with probation, the court will enter the conviction and discharge the defendant.
