Yes, IB can do exactly what you want. Give them a call and explain and they will set you up.
You could just setup a conditional order for the limit(target) that gets placed if the market moves under or above X price.

An attached stop order is the best solution.
I would refrain from a conditional order. Just because the market reaches your limit price, there is no guarantee that the limit order is actually filled.
