Image roll over AND drop down menu's

I am tyring to shoehorn a drop down menu that a client wanted (oh by the way/last min thing) in to a design that has roll overs. I have not found any good (ie less than $40+ if not just free) solutions. I just want to get this done, and I do not really have a budget to go and buy/licence a solution that should just be out in the wild. Do you all have any ideas?
