Backing Choir Vocals for a Indie/Rock song

Looking for backing choir vocals for an indie rock song. No hard deadline on delivery. The song currently has a male vocalist. Choir vocals would be uncredited on the song but I can credit you on socials etc. I love how James Arthur uses choirs in his song ‘SOS’ or there is an artist called Cian Ducrot from Ireland and he uses choirs greatly

Additional info:
The song will be released commercially. I don't have a hard deadline for this. I don't need to use your name - you can be uncredited. The lyrics and melody are already written. I just need a singer.. I'm looking for a female singer. I need all the vocals recorded (lead vocals, harmonies, stacks, ad libs).
