How much does it cost to hire a prosecutor?

Answer 1

Unless you're a government agency, you won't be hiring a prosecutor per se. Attorney's fees vary considerably, but in the US you can reasonably expect to pay a few hundred dollars a hour for an attorney's time. There are also various fees you'll have to cover... for instance, any time you file documents with the court, they'll charge a filing fee which you will have to pay on top of the attorney's fees.
