Help obtaining Fenrir ^^;Follow

I am currently seeking lvl 75 help in fighting and defeating Fenrir! A good cohesive LS or group who have succeeded in defeating him before would be greatly appreciated ^^. If you or any of your friends would be willing to help me out please contact me in-game: Wizzaruru 65 BLM (SMN is 41) Thank you in advance, and if payment is necessary pls send me details in-game.
