In reply to Nedediah:
We run a lot of bespoke instructional courses all over the South West, plenty to be going at without it being too scary or require any gymnastics!
Feel free to have a look at our courses here...

We don’t tend to have many open courses where several clients who don’t know each other all come together, generally because the dates and learning goals don’t match up, although if you find some others to join you then we can of course accommodate this.
There are a few of us around the County (including ElSwiftos who has already replied). Whoever you choose, look for an AMI (Association of Mountaineering Instructors) logo.
Have a look as well at the BMC Ready to Rock Courses - these run all around the country and are designed to get indoor climbers outside - maybe not quite your situation, but you may find them a good place to meet other people who may be interested in then bookin further instruction.
