PPL theory exams passed, written off by your FI for solo, done the x-country training sessions and now talking of the last few hours to build?
Just do it at your home field, cannot be much hours. "Finishing off hours" usually is something like less 5 hours missing.
If you are talking PPL theory exams passed, now looking for a place to do the practical training, it is a totally different story.
How many hours and much more important, how many training sessions from practical syllabus are you talk missing?
