Disguise alignment

Hello all,

My character is an Aasimar Celestial bloodline Sorcerer. He's also an evil-aligned socialite who thrives on abusing his heritage's reputation to gain peoples' trust and then manipulate them. I am looking for a way to disguise his alignment as Lawful Good. Bonus points if it can be done within the first 5 levels or for under 1000 gold. The campaign hasn't started yet and if I can't start with it, I'm going to try to make finding such an item my first quest. Can't have any pesky Paladins outing me, now can I?

Yes I know about Misdirection and undetectable alignment. I want him to consistently read as Lawful Good. Neither of these spells can consistently do that.

Considering most characters under 5th level don’t have a detectable alignment you would be better off not detecting a specific alignment at low levels. If you have Champions of Corruption the feat Mask of Virtue sounds like it would make it so that your alignment is not detectable.

Angel hide or angelskin armor can mask your evil aura. It's about +1,000 gp for light armor.
It won't make you detect as good unless you know they're detecting for it, then you need to be seriously considering an action with good intentions, but it would legitimately have to be an action you are intending to do, as detect good will detect good intent like detect evil detects evil ones, even in a non-evil creature.

My character is an Aasimar, an Outsider, which means I get an aura at level 2. As far as mask of virtue is concerned, My DM is higly likely to make me roleplay the fiendish pact for mask of virtue ingame after I find a demon to pact with. I doubt that would happen at early levels.

Ditto the Angel skin. I'd have to find it ingame. He's a stickler for rare things to be found ingame and roleplay their discovery. We've had to quest to find adamantine and mithral in previous campaigns because "why the hell would a human smith in a town like this who fixes plows for a living have a store of mithral large enough for full plate just on-hand whenever? No, there's a dragon in the old castle/dwarven settlement under the northern mountain range/bigger market in the capitol to the east, go find some g%*$~%n mithral and bring it back."
