Need plumbing help to unclog kitchen sink drain

Hi there, I’m looking for a qualified person to unclog my kitchen sink. The drain has been slow for a few days and now it’s completely blocked. I’ve tried a plunger and a basic household drain cleaner with no luck. I’d prefer a professional who can assess whether it’s a simple blockage or something deeper like a trap issue. Please include any required safety steps, the tools you’ll bring, and an estimated time to fix. I’m flexible on the start time but would like it completed today if possible. Located in [city/area].
