Please could someone help me get op levels?

I have just got to 72 and was wondering whether someone could help me with the process of getting to op8. I don`t really know what I would need to do and I would be doing it alone so any help would be very gratefully received.
My PSN is COMPLETE-ANIMAL feel free to drop me a message or friend request.
Thanks
