Need help replacing a door handle and latch

I’m looking for a skilled handyman to replace a worn door handle and latch on an internal bathroom door. The current handle is loose and the latch isn’t catching properly. I have the replacement handle kit (supposed to fit standard 2-1/8 inch spindle) but I’m open to advice if different sizing is required. Please bring basic tools, take care not to damage the door, and ensure smooth operation. I’m hoping for a tidy install with minimal noise and disruption. Availability to start mid-morning this week would be ideal.
