Seriously I think the best solution is to just take 1 level of Cleric to get Cleric spells on your Spell List and thus able to use Spell Trigger Items such as wands and then just uses these spells (combine with Jack of All Trades).
Assuming 1 level dip into Cleric, and Jack of All Trades
+1 Int Modifier(Jack of All Trades requires Int of 13)
+2 Masterwork Item
+5 Tome of Worldly Memory, Competence Bonus
+8 Wand of Divine Insight, 2nd level Spell. (Divine Insight is 5+CL and since you need CL of 3 to cast 2nd level spells, the total is 8), Insight Bonus
+5 Wand of Sacrificial Skill, 1st level Spell, Untyped Bonus
+2 Ceremony conducted on an Altar, Circumstance Bonus
+1 Subject has 1-5 HD, Circumstance Bonus
Thus you will have 24 for the modifiers before the 1d20 roll. You always roll a 1 or higher, thus you will always make the DC check of 25
Now the cost per day for this is the charges you use from your two wands. The market price (not the crafting price) of a wand is as follows 750*Level of the Spell*CL. You are using 1 charge per day thus the total cost per day is 15*Level of the Spell*CL
Well you have one 1st level spell at CL 1 (Sacrificial Skill), and one 2nd level spell at CL 3 (Divine Insight). Thus the total cost is 15gp+90gp for a total of 105 gp per day. I consider this to be damn cheap.
Don't like expendable items, then get your DM to allow you to make eternal wands of these spells (820 gp for 1st level, 4420 for 2nd level). Now normally eternal wands are only arcane spells, but this rule is silly for the pricing of eternal wands are based off the guidelines located here
http://www.d20srd.org/srd/magicitems/creatingmagicitems.htm Eternal Wands are command word items with a cost of Spell Level*Caster Level*1800gp/Divided by Charges per day. Only difference is that Eternal Wands can be used two times per day while the normal prices would only allow 1 use per day at those price, in exchange Eternal Wands can be used via people who have some form of arcane training while people such as a fighter needs a UMD check.
Now a 1 level dip into Cleric has the added benefit of gaining two domains or two devotion feats.
