First build of a guitar and a slight problem

Hi Johnny, mark up the pickguard what you have to cut and clamp it close to the cutting edge and a small saw or hacksaw should do the trick. Try and support the other side not clamped as they break pretty easy. Sand the edge.
Check the offsets of the PG to the edge of the guitar when you mark it up and place the pickups in a position you think will be final, allowing enough space for the neck heel and surround

Isn't a hand scroll saw like this with a very thin blade the most precise to use?
