If your guides are good, you still probably only have about a 0% chance of success. The reality of Nepal and climbing in general is that they will most likely take your money and take you to the mountain, but they will likely not risk their lives actually making a summit attempt on K2 with someone so inexperienced.

>>466363If you do Denali with a company, then the main things you need to know are how to handle living in the environment for 2-4 weeks, and how to follow orders so you don't endanger yourself or anyone else. Get some experience winter camping, snowshoeing, and hauling a gear sled.
Smart companies will require you to provide a list of your experience in order to agree to climb with you. You want to climb with a smart company because not only will you probably have better guides, but other clients that you will be with will be smarter/more experienced as well.
If you really want to do Denali, and you have the cash, I recommend taking a general training course from one of the companies that does the actual climb. Last year I did a 12-day course with Alaska Mountaineering School and it was a great intro to the Denali region and the skills needed; at the end the lead guide invited me to join them on Denali this season since they were happy with my performance on the course. Unfortunately I have been having health problems so I am not confident in doing a big climb this year.
