Do an audio cover for the song Strawberries & Cigarettes

I'm looking to re-create the vocals and potentially the instrumentals for the song Strawberries & Cigarettes. My singing voice is not the greatest so I'll need help to artificially adjust it to (1) make it sound better and (2) to fix the tones. I've put a sample of what my voice sounds like. I'm sorry in advance for the terrible sounds you're about to hear.
