It took us like 5-6 tries in that group. Also you don't need a group with everyone from the same company for it. All that does is give you more seals as a reward.
The Toto-rak quest should be very simple for you two to duo. The enemies should be within XP range for you guys and you don't have to complete the dungeon to finish the quest. All you have to do is get far enough to open one of the gates, no matter which one you open the quest NPC you need will be behind it. The hard part would have been to find at least 1 other person to enter with but since you're a duo team you have that part covered :p
