You could go with a fixed firm price, but ultimately you might pay a bit more than it otherwise would have cost to have those assurances, as they'll pad their bid to cover unknowns.Unless you're willing to pay a bonus if they come in under time (and of sufficient quality) I'd be hesitant to try and push a penalty.
