Window Hinge Replacement Needed (2 Windows)

I need help replacing the hinges of two windows in my apartment. One of the windows is shown in the attached photo — it uses a top-hung friction stay hinge, which appears to be worn or damaged. Both windows need new hinges installed. I can provide the replacement parts, or you can include them in your quote. ???? The apartment is on the third floor, but the work can be done from inside — no exterior access required. Please bring the necessary tools. Flexible with scheduling, preferably during weekdays in the morning or early afternoon.
