Sometimes the best approach to your concerns is to find two separate surgeons, each specializing in one or the other procedure. Combining the procedures at the same time may be impossible and it may even be medically a bad idea since the rhinoplasty is a less sterile procedure than breast surgery.
Fees vary widely, so you'll need to call some offices to get an idea. As you compare prices, though, make sure that you're comparing apples to apples (i.e., that the fee includes anesthesia and facility fees). Also note that neither the least expensive nor the most expensive surgeon is necessarily the best.
Put far more effort into researching the surgeon and reviewing his/her work than simply comparing price. Since you're in Florida, the state medical board has a very extensive database available for free to the public to check the background, training, board-certification, and criminal and med-mal history of the doctors in this state. Just google "Florida Medical License Lookup" and you'll see links to the Department of Health's website for the database.
All the best,
