Mt. Hebron Victory Faith Center Church - Getting paid for church gigs?

Hello,
I play alot in churches in my area, especially my own, but none of them pay anything. I happen to be a poor college student scrapping funds together to try and pick up a good C trumpet for orchestra and quintet so you probably see where this is going. Don't get me wrong I love doing it but these are the kind of churches where they like to have people play for their services and don't offer any anything, so I don't ask. So my question is this, is it ok to ask to get paid in this kind of situation? I get the feeling that they would'nt want me back if I started asking for compensation, but I really need places to perform...
Please help
I didn't find the right solution from the internet.
