Have your walked yourself through the Getting Started document? See how you go. Post if you have questions about how to operate the PCB editor. A small run of PCBs is incredibly cheap anyway.
BTW your schematic is not ok. You have ERC errors in it and I think you have a short across a capacitor.
PS: There are also paid and free video tutorials on the Interwebs but make sure you don’t watch an obsolete tute or you’ll waste your time.
