Reusing your Chest, Belt, and OH, I looked through the AH and came up with a 110k dps, 500k EH, 421 LoH, 5.3% LS set for 288.5 million. At first I wanted to get an EF with lifesteal, but given that your OH is a dagger (slower weapons get more benefit) and doesn't have any CD, it was cheaper and more damage to just get a rare.
I was disappointed with that dmg, and just switching up the amulet to one without LoH added 6k dps.
Interestingly enough, I only spent about 108 on the gear itself, it's the weapons that hurt. I think to really get the best outcome you'd probably want to replace your OH, at the least, with one that has CD and then maybe think about switching out your belt for a Witching Hour (this would also allow for more options in weapons since you wouldn't need physical dmg ones to take advantage of the +Holy dmg on the belt). And again, this was just looking through what is currently available in the AH and only using buyouts, so you could probably get better stats for cheaper by using bids (or having a better idea of what you were aiming for!). I guess it's also worth mentioning that since I had 350 million to spend, I didn't look for the best deal once I got to the weapons ... I simply spent what I could afford to.
