IMO having PCBs manufactured takes for ever, and can be expensive. It could take a month for you to get your board!
I highly recommend learning how to do the 'toner method'. Someone here has their own tutorial on it... Pretty much you would make your design in Eagle, print it out, apply to copper board, then submerge in special solution. (It's a possibly dangerous acid). It will remove copper and make your traces. Then theres the drilling holes for your components. Of course if you do SMD, no drilling! Finally, populate your beautiful board!
You can even color it! (Red looks cool) Search hackaday for that article...
Hey! Sparkfun has a tutorial on making schematics in Eagle, then creating a board layout with it:

Lecture 9 - Eagle: PCB Layout
Here's the link to Eagle:
