FOI - How much taxpayer money has the CPS spent in prosecuting Paul Chambers?

Like many, I'm personally disgusted with the sheer waste of time, money and resources being spent by a public body (the Crown Prosecution Service) on the prosecution of a blameless individual. How much money is it? I'd like to know. Therefore, I have made a request under the Freedom of Information Act to the South Yorkshire office of the CPS for disclosure of all the information related to the costs of the prosecution. I've directed my request for the attention of Roger Tricklebank, a Senior Crown Prosecutor with whom I've had communications in the past, and copied Naheed Hussain, the Chief Crown Prosecutor for that region. I believe that I worded my request clearly and properly, and therefore we should have an answer within 20 working days unless the CPS require more time. Though it's hard to imagine how they would require more time.
