The Teamwork section of the forums is more appropriate for this kind of thing, so I've moved your thread there for better results. Hope you find a Dungeoneering partner soon!
In order to be somewhat efficient, it's usually best to form 5-man parties, but this is not all that easy at lower levels. Parties are generally quite hard to find if below 60 dungeoneering, as this is the level that unlocks the high Abandoned theme floors, which mostly everyone does as their lowest floor.
It's worth noting that the skill can be very slow if you have "low" stats, so that's something worth taking into mind. I would only recommend you jump into the skill, if you have a certain goal, e.g Bonecrusher or a level needed to unlock a new area in the game.
I'm quite fond of Dungeoneering myself, but unfortunately I'm a special build and don't want experience in Summoning and Prayer. So the XP rates may be lower when dunging with me than others...! I'd however be up to do some floors with you, if you give notice beforehand.

the good times,

from the negatives, and if things don't work out,
take another shot
