Where can you place a futures bet that a team will win 5 games in a row?

I'd like to place a bet that the Denver Bronco's will win the next 5 games in a row. Is there a book that will take that bet and how do you do it? I know I could double up each ML bet won but there's got to be a way to parlay the wins for higher odds

I know the Bronco's schedule is brutal and they will probably be dogs in 4 of the 5...
