In reply to Os_878: Any experienced Mountaineering Instructor would be perfectly happy to run some bespoke training for you. With two students, a difference in ability/experience will not be that much of an obstacle to worthwhile instruction.
You can find a fairly comprehensive list of fully qualified instructors via the Association of Mountaineering Instructors -

Equally, if you want a couple days instruction in the Bristol area during March or April, you are welcome to email me via UKC.
