Install New Garbage Disposal Under Kitchen Sink

My kitchen garbage disposal has finally given out after years of use — it hums but won't grind, leaks from the bottom, and the whole unit rattles badly whenever it's switched on. I've already bought a replacement (a standard 1/2 HP disposal unit that fits a standard sink flange), but I don't have the plumbing experience or tools to safely remove the old one and install the new one myself, especially since it involves working with the electrical connection, the dishwasher drain hose, and the trap underneath the sink.

I'm looking for an experienced, licensed plumber who can come to my home, disconnect and remove the old broken disposal, inspect the sink flange and plumbing for any wear or damage, and then properly mount and connect the new unit. The job should include checking that the dishwasher line is reconnected correctly, that there are no leaks anywhere in the drain assembly, and that the disposal runs quietly and grinds properly before you leave. I'd also appreciate advice on general maintenance to help the new unit last longer.

The kitchen is easily accessible, there is a cabinet under the sink with enough room to work, and power is already run to an outlet nearby. I can be flexible with scheduling on weekdays or weekends, whatever works best for you. Please bring your own tools and any small parts you expect to need (plumber's putty, mounting hardware, wire nuts), since I only have the disposal unit itself on hand.

Requirements:
— Remove and dispose of the old broken garbage disposal unit
— Install and secure the new disposal under the kitchen sink
— Reconnect dishwasher drain hose and check for leaks
— Test unit for proper operation and quiet running
— Licensed and insured plumber preferred
— Bring necessary tools, sealant, and mounting hardware
