Rossco,
Gonewest is right in that the best place to start would be your local airfield, if you aren't rushed for time you can study and take the exams at your own pace.
If it is pretty imminent that you get them passed the only guy I know is Ron Heyter down at Bournmouth Airport. he does a 3 day groundschool and exams with the exception of the RT which he is not licenced to undertake so you will have to get that done at your local school anyway. He was charging about £300 all in about 2 years ago but not sure what he charges now.
Julian.
