Can someone point me toward some free online jazz theory lessons. Ive searched for a long time without results and I dont have enough money to buy books yet. I just need a resource that can get me started with Jazz theory.

Also, can someone help me with minor versions of the 7 modes? I used my knowledge of theory to create minor (b3, b6, b7) versions of the Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, and Locrian modes that span the fretboard.
