Simple Broadway tune needed

[*sigh*]

Hi there, I'm *sigh* and I'm a singer. Well, half of a singer anyway, I just made up the vocals for a Broadway-esque song called "Good Morning Celestia" but I'm at a loss when it comes to anything instrumental. (Also I'm poor and can't afford any of the software/hardware)

If anyone could provide assistance or even be able to direct me toward sound files with the kind of stuff I'm looking for, then that would be awesome.

Free composing software, no good hardware needed, only a little bit music theory:

Else it will be a VERY hard work for both sides, trying to figure out what you want it to sound like, which could end up in a 2 year term of sending files back and forth... and I don't think someone here wants that :/
