I have some good news for you, assault 4 is a misdemeanor offense, the lowest level of criminal offense in the state of Oregon. As such, and with your lack of a criminal history, you should be facing some fairly light penalties.
One thing you may want to check into is the possibility of a diversion program. Such programs are usually offered for low level offenses where the defendant has little to no criminal history, such as your situation. Diversion programs typically have you complete some penalties, such as community service and anger management classes, in exchange for a dismissal of the charges.
If you are interested in retaining an attorney, you should begin with your state bar association. The Oregon State Bar has a website, it is located at www.osbar.org.
I do not know your county of residence but your county bar association likely has a similar site that will be more specific to your location.
Additionally, Martindale Hubbell is a national organization that rates attorneys across the country. Their website is located at http://www.martindale.com/.
Another nationwide website is located at http://www.avvo.com/. This site lists attorneys by geographic location and area of practice.
Each of these resources will have a wealth of information as to attorneys in your area that handle such cases. I would suggest you check each site out and you will surely find a great number of attorneys that meet your needs. Pick a few to meet with in person so that you can thoroughly explain your situation and then retain the one that you feel can best represent your interests.
If you can't afford an attorney, you may qualify for a public defender (PD). If that is the case, simply go to your arraignment date and let the judge know that you can't afford an attorney. The judge would likely ask you a few questions about your financial situation and then make a determination as to whether you qualify for a PD.
