How to craft an album

I'm working on my debut album and want to develop a unique sound, but I don't play any instruments. I have a raw vocal quality and strong songwriting abilities, and I'm inspired by producers like The Neptunes and Jimmy Jam & Terry Lewis. I'm using GarageBand and plan to blend futuristic, experimental elements with live instrumentation (even if it's sampled). My main challenge is building beats, melodies, and atmosphere without playing an instrument myself. For those who have crafted albums solo, how did you shape your sound? Did you use loops, samples, or collaborate with producers? Is there any producers willing to work with me ? Any advice on arranging songs, directing production, and making everything feel cohesive?
