You probably won't do well.
Err. Cruel Fanged Knife of Quickness or Cruel LEgend Spike of Quickness.
Or possibly a Cruel Bone Knife of Quickness. (1 socket max.)

You won't do good due to slow attack speed, low damage, low attack rating (not too low, tho.)

Poison dagger at lv 30 is only 19x poison damage for 2 sec, 305% AR.

...Necro doesn't have to go melee, they are way better using BS and such skills.
