Base: nekro (good passive aoe dmg, armor reduction etc)
Hb: h.fenris (good armor/dmg/stats overall) fatima (works fine as well if gonna use dmg lixs)
Aa: nekro/magma/whim/fatima/ww

Those are within ur budget range, are the best I could think of atm.

I wouldn't use either elektra or hiberio, they are just vanity pets for dmg stat.
