Mostly straightforward stuff:
+2 weapon: 8,000
Daylight 1/day: 5,400 [(5x3x1,800)/5]. You might give a discount on this because of the activation method.
That leaves 36,600 for the funky stuff. +4 vs. evil isn't worth as much as a +1 enhancement, IMO; however, that double damage vs. undead and negative energy creatures is very nice. Honestly, I'm not sure how to price that.
