Actually, a simple sling with two legs about ten feet long would let you pick this thing up from a single point and keep it horizontal. If the object is too fragile for this, the answers normally used are: - longer legs - more legs on the sling - a strongback which could be something as basic as a galvanized fencepost or a 2x4 stud with a couple of weights on it.
