Item that detects evil

[Sitara]

Basically I want the costs of a brooch OR amulet (whichever is cheaper) that can :

cast the detect evil spell at will
cast the detect evil spell 1/day
cast the detect evil spell 3/day

If there is an official item already made please point me to it (i.e. the product name and some details)

Well, for the first one, it's called "being a paladin."

http://www.d20srd.org/srd/magicItems/creatingMagicItems.htm#tableEstimatingMagicItemGoldPieceValues will give you the formula you need, just plug in the numbers and do the calculations.

Since magic items tend to be less expensive now (with Magic Item Compendium) than a stick formula usually gives you, I would make it a priority to find the same or similar item in the Magic Item Compendium instead of using the formula. The formula was never really very good...

Rod of Alertness or
Good-aligned Intelligent Item with a Greater Power of detect (opposing alignment) at will

(Also, a Phylactery of Faithfulness might sometimes help if used cleverly)

In MIC, there's the Lens of Revelation for 1400 gp. It's in one of the divine item sets, just check for it in the back listing, under eyewear/face.

I don't know... Using the DMG rules and some "common sense" consensus with your DM on proper "body slot," 1000 gp for a pair of Detect Magic goggles, usuable at will, is pretty sweet. Heck, even paying 2000 gp for a stone of Detect Magic that you keep in your pocket is nice.

Formula used: 2000 gp (continuous/use-activated item) x 1 (CL) x 0.5 (cantrips count as "half level") = 1000 gp.
