Looking at it more:
Dusty Rose Prism Ioun Stone (5k gp) + Wayfinder (250gp) gives a synergy of a +1 insight to CMB/CMD for 5250. This item uses the (bonus squared)x2500gp formula, and additionally gives you +1 insight to AC. Insight is a powerful bonus, but untyped is the most powerful type of bonus. so this is probably a little better of a place to work with.
an item of continuous Resinous Skin would be 45k. Not the best price, and there are ways to cheapen it like giving it uses per day rather.
an item of continual Lockjaw would be 48k. same as above in that it could be made more cheaply by doing uses per day or whatever.
the second spell does give a larger bonus, however, but it is untyped. the first spell gives some other side buffs.
The best comparision if you want to do it for untyped would be Gauntlets of the Skilled Maneuver. That is 4,000 gold for a +2 untyped bonus to CMB for a specific maneuver. Or basically bonus^2*1,000.
At most a circumstance bonus to a maneuver should cost that. Honestly if Voice is okay with it, the couple items I was looking at I can re-engineer using the cost of the gauntlets for the slotted ones, and double that for the slotless ones. I had completely forgotten about the gauntlets till a friend reminded me about them.
