Can you please recommend the best discrete carpet fixer/cleaner in PDX?

For context I am set to move out and I did not realize a stain I thought would come out was made worse by what I was using to clean it out with. That was totally my mistake. Problem is my leasing office won’t do spot fixes and would charge me for entire carpeting (think over $500). I cannot afford to lost all of my deposit on this and need professional help at this point. I have some monies stored for emergencies and to me this seems like something I need fixed. Please don’t judge me, its been a rough year (most everyone has had it rough).

I ask for discrete (the most as possible) as the apartment has a list of only people they recommend but I cannot go through that process as I mentioned they require the entire thing to be replaced and again, cannot afford Deeply in debt and lets just say I don’t need to add more.

Thank you for reading this and I hope you are doing your best.
