Selling Heroic Emerald Nightmare

Interested in selling Heroic EN next week before Nighthold releases to get some funds for our guild bank, Master Loot. Anyone have experience doing this? Mainly not sure what to price it at and if it would be viable/how to handle bringing more than 1 carry for the jewelry/cloak conundrum.

We're 7/7 1/3M and can easily smash Heroic EN, just haven't sold before now since no one took it upon themselves to organize runs.

Any advice would be appreciated.
