Get my voice and song ready for a live singing performance

Help me get a song ready to sing live. Song and original artist: [TITLE - ARTIST] Event: [open mic, wedding, school concert, outdoor gig, karaoke night - crowd size, indoor or outdoor] Accompaniment: [backing track / guitarist or band / I play myself / a cappella] My voice: [range if known, voice type, training, where the song feels hard - e.g. "chorus feels too high", "run out of breath in verse 2"] Sound setup: [house PA with sound person / small speaker / no mic / not sure] Time until the performance: [e.g. "3 weeks"] Give me: 1. Key and fit check: how to tell whether the original key suits my voice, how to test and choose a better key (and tell my accompanist or change the backing track), and simple arrangement changes - shorter intro, lower harmony line, softer bridge - that play to my strengths. 2. Problem spots: for each hard section I named, a specific practice method (slow practice, breath marks, vowel shaping, singing on a lip trill first). 3. Rehearsal schedule: from now to the show - sections, full runs, practice with the accompaniment, and at least two full run-throughs standing, with a mic or a stand-in, as if live. 4. Vocal care: a 10-minute warm-up, breathing for long phrases, hydration, and what to avoid in the 24 hours before. 5. Lyric security: memorization techniques and a plan for what to do if I blank mid-song. 6. Mic and monitors: mic distance for loud vs. quiet passages, avoiding feedback, what to ask in the sound check, and how to signal that I need more of myself in the monitor. 7. The last 30 minutes: a short warm-up and calm-down routine. Don't reproduce the song's lyrics; refer to sections like "verse 1" or "the bridge". If I get hoarse, lose my voice, or feel pain when singing, tell me to rest and see a doctor or voice specialist rather than push through.
