The only thing that really bothers me about that video is the other guy coming up too and the tools in the bag below. If I am going to do a job like that, I do not want someone else up there that I have to watch out for. I think the tools ought to be cabled to the tower and already up there. Lastly and I'm sure this would make it illegal. I would base jump off to go down.
Heights don't really bother me, but I will admit, my arms would be very sore after that climb because I would be gripping pretty tight.
Oh, and yes, I would expect a freakish load of money for doing that.
