If you have done so much research I am not sure how to help ?

To crack a WPA2 key you need the handshake, provided by aircrack-ng suite using airodump-ng.

Then you need a LOT of computing power to run an attack against the handshake.
(you could use rainbow tables)

Personally I would l use a phishing attack against an access point to gain WPA2 keys, I have had a 70-80% rate of success

Here are two WiFi Phishers - https://github.com/wifiphisher/wifiphisher or https://github.com/FluxionNetwork/fluxion

Good luck!
