In reply to Rob Parsons:
The impact that setting a ledge up well has is the same as a trad lead.
Why shouldn't this experience be open to more people to have a glimpse into our world?!
And of course a professional mountaineering instructor is going to charge for that service!!!
Don't be too quick to judge and publicly name reputable professional instructors on a subject you're clearly way out of touch with.
I am biased as I also run guided Portaledging, but you can rest assured those of us that work in this industry care more for the environment than most, and will do everything within our power to minimise our impact on it and instil this ethos on those we take out.
The price may seem expensive but the cost of the kit, insurance, qualifications and phenomenal, and time and effort to get the personal experience to run these activities considerable...
You owe the guys at Gaia and Sam and Will an apology...
