Good day. I need full string arrangement and performance for a gospel track

I have a tuff demo vocal with a piano sketch. I think the song just needs an orchestral accompaniment. Would love to know your rates.

Additional info:
I need the mixer to do some editing, time aligning and vocal tuning before mixing. The part I'd like you to record is already written. I'll need you to master it too if possible. I need it by 1 April, 2023. I'm interested in working with a very experienced mixer. I'm an indie artist. Check out the song I attached.
