Start-up Idea: Selling Experience

I currently manage an investment blog called My $10,000 (www.my10000dollars.com). Over the course of my blogging days, I've learned that my interview series are by far the most popular and interesting posts. This led me to an idea - selling experience.

What if we created a platform that allows people with various experiences to "sell" their experiences? If you were an aspiring mountain hiker who wanted to conquer Mount Everest, would you be willing to pay some fee to talk to someone who's had an experience climbing the mountain?

Or if you were an investor who's lost most of his/her retirement fund in the financial crisis, would you want to talk to someone who went through the same disaster but recovered from it?

Haven't thought through all the details on execution, but I'd thought I would share the thought and seek your input.

Why am I sharing this with the public? Well I have other endeavors I'm pursuing and won't be able to focus on it even if this idea was viable, so why not share it with others who could potentially take this and run with it, right? :)
