Help find bonuses to d20 rolls

[Aemoh87]

I wanna optimize profit rolls using business rules in dnd 3.5 (see DMG 2), I have merchant prince and the feat savvy. Any random bonuses I can easily tack on there?

I have heard that feats that add +1 to a d20 roll work, or some human only feats.

get a wish for one
that should help you
if you want to gain profit then you might want to put ranks in proffesion (business)

One of the feats from Races of Destiny, Heroic Destiny (?), is indeed a human-only feat that lets you add 1d6 to any d20 roll, 1/day.

I am talking about the business rules out of the DMG2. You make a profit check to determine how much you make, I want to optimize that.
