This guide explains 3 ways to move to nullsec:
1) Switch your Home station via the Corporation Menu --> Home --> Details
to our Office in OP7-BP and self-destruct your capsule to respawn there.
(click on the image to open it in fullscreen)
2) You can make your way to OP7-BP in an Interceptor built for Traveling (aka less than 2 second align time).
Make sure to use either the Malediction, Crow, Ares or Stiletto.
3) Make your way in a cheap frigate built for speed and align time.
This is more risky but if neither of the two option above works for you you can try this one.
