I'm looking for a producer to do additional production on a few songs

I'm an artist and producer. I'm working on some new material and I'm looking for someone who I can work with to do some additional production on 3-4 songs. In terms of references I really love Jack Antonoff's work, particularly on Lorde's Melodrama and St Vincent's Masseduction. I'm also a big fan of Sounwave, Grimes + Tay Keith's production.

Additional info:
. The lyrics and vocal melody are already written. I'm an independent artist not affiliated with a record label. I have a song already recorded and want some additional production elements - sound effects, synths, samples, percussion, re-recorded instruments. I will be recording vocals on my own. I'll hire a different pro mixer and mastering engineer, for the moment I'm just interested in production. I'd like to work with a top pro who's worked on hit songs and I have the budget for that. I'm looking for someone to record some additional sound effects, short drum loops, or other production elements. I don't have a hard deadline for this.
