You won't find anything for £30K that meets the mission spec.
What you will find is a lot of undermaintaned old dogs who's owners will tell you that their aircraft will do the job if you just add fuel & oil.
No doubt there will be a number of posts below telling you of aircraft that will do the job but 99% of it will be hot air from people with old dogs to sell or the new generation of underbuilt ultralight toys.
