Heh, yeah, hardest combo certainly, as burgs take time to setup their attacks, in mêlée range. By the time they are ready to go, a hunter would be done and gone.
That being said, let's take on this challenge! :-)
One idea, burg is in stealth ahead of the hunter, but turned around to face the hunter (back to MOB). Hunter shoots MOB. MOB comes running up to hunter, oblivious to burg, who could Aim and backsta...oh wait, the hunter already killed it.
Let's see... The hunter could wait, the burg sneaks in behind a MOB, Aims and one-shots it.
Ums, how about you coordinate different targets? The burg could sneak up, attack, if there are multiple MOBs, the hunter could take down one of the others, this would keep most MOBs on the survivable burg, and the hunter would never get overwhelmed/have to run. The key will be to watch out for CC the burg applies (slumped over MOBs with grey swirly overhead are mezzed).
Realize a liability is you both wouldn't be tagging all the MOBs this way.
If you are both weak, and not outright killing MOBs readily yourselves, or in an area with signature or elites, then probably easiest to have the hunter pull, burg mez a ranged one, and both attack the same one, the burg applying tricks accordingly to increase your damage or decrease the incoming damage as appropriate.
The burg can also trait to have Enrage force a ranged MOB to come into mêlée range, the key will be sure threat stays on the burg then.
Basically just talk with each other, and have patience as a hunter for setup time, with all the CC and buffs and heals and DPS the burg provides, it could be a powerful combo.
