Profitability: minimal. 20 gold for killing the bosses, plus 20 or so gold from vendoring drops.
Not much to this raid, really.
High King Maulgar
This fight is actually a bit tricky if you have low DPS, due to the chain fear/polymorphs inflicted by the warlock and mage. If you have to choose, take out the warlock first.
Big. Ugly. Kill him.
