musictheory.net - use the lessons and exercises because you have to know the basics of reading and memorize the key signatures, etc.

I urge you to check out Hal Galper and Mike Longo's books/videos. They are at the forefront of Jazz Education and their material is a rite of passage for beginning jazz musicians.

Here's a playlist of Galper's masterclass videos:

The best general jazz chord-scale theory text I've seen (I've seen them all) is probably the Berklee book,
Chord Scale Theory and Jazz Harmony;
However, even better would be the Bert Ligon books, because they go into more detail about how to actually put it into practice:
Connecting Chords with Linear Harmony
Jazz Theory Resources Volume 1
Jazz Theory Resources Volume 2
Comprehensive Technique for Jazz Musicians


P.S. this subreddit is geared more towards jazz listeners and may not have that many musicians.

I'm a guitarist/programmer and recently tried to deal with the same problem. You can check out my efforts here. Would be interested to know what people think. The naming conventions are taken from this Berklee book called Chord Scale Theory and Jazz Harmony. It's not finished, I'd like to include slash chords and I haven't tested it extensively.

Simple.
The iii and vi can act like a tonic. The ii like a sub-dominant and the viio like the dominant.
You can add whatever (The 9th, 13th, 11th) to whatever chord as long as you like it, they are ornaments, very nice with dominants.
Just experiment man.
Also check out this book http://www.amazon.com/Chord-Scale-Theory-Jazz-Harmony/dp/B000M7B65O
It has substitutions explained very clearly. Jazzology is another cool book.
If you know where to find you can get them like...freely cheap ;)

EDIT: Almost forgot substitute dominants! wtf. Just substitute any dominant for another dominant a tritone up, so it resolves a half-step down. The reson it works is that it conserves the tritone that gives the dominant the character. Also, you can make ANY chord dominant in order to "tonify" a certain chord for a moment, that is called secondary dominant.
There is a chance I'm mix-matching those names btw.


EDIT 2: Try asking this in /r/musictheory.
