Advice on Eviction Process in Chicago. IL

[Regina Bailey]

I'm a landlord dealing with a tenant who has been unresponsive for the past month. She is currently late on rent for the month August and still owes a remaining balance of $100 from the previous month. I've made several attempts to personally deliver a five-day notice but haven't been successful. Despite my efforts to reach her by phone, email, and text, it has been nearly impossible to get in touch. I'm at my wit's end and really can't afford to hire an attorney. Do you have any advice on how to start the eviction process? Thank you.
