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