I have a friend in la who is a producer and wants to sign him to his record label
What is it that you need to know?
I need to know what he wants for this. What are the benefits?
Helping others is not only good for them and a good thing to do, it also makes us happier and healthier too. Letting your friend in LA know about him will help them both in the long run.
I hope he knows he'll owe me for this!
You should help your friends because they're your friends, not because you want them to owe you favors!  You'll find yourself without many friends if you keep that up.
