Imagine the following scene:
*Phone rings*
- Voice #1: "Hello, is this the recording studio? I have a really good idea for a song. Could you guys help me record it?"
- Voice #2: "Well, certainly. Can you send me a bit of your previous work, so I have an idea about what I am dealing with?"
- Voice #1: "Previous work? No, no, you don't seem to get it. I haven't actually recorded any songs before now. However, I am hoping that after you guys help me record this song, I will be able to buy a guitar!"
Voice #2: "So, let me get this straight: You haven never recorded music before, you have nothing to show me, to tell me that you are a capable musician, and you don't own a guitar of your own, and you expect me to give you financial support with your song?"
Voice #1: "Yep, precisely!"
*Disconnected*
This is pretty much what you are asking of people. Just saying.
