One of the unfortunate and fortunate things about P1999 is that its more efficient to farm a couple of items and buy loot that should be way out of your ability to acquire (Seb, HS, etc etc).
So the question becomes what things can you farm to get that loot...
Some things that may be doable in a couple of levels:
Shralok Packs -

Glowing Black Stone -

Goblin Gazughi Ring -

Lots of other low level mobs to camp...
My personal choice is Pyzjn, easy to spawn, lots of mobs nearby to level up on in the day time. Have managed to get 3 orbs so far so 6k in pp which is pretty okay for me. Enough to gear me out with basic gear. I updated the wiki with her spawn info so its current if you want to try it.
