For $2,000, professional skateboarder and videogame character Tony Hawk will call you, answer any question you have or change the outgoing message on your voicemail. For a little more, he will go Go-Kart racing with you, play mini golf, escort you to Disneyland, or even show up at your school.
From his website http://www.tonyhawkexperience.com/
“For the first time ever, you can spend the day with Tony Hawk and his friends in some of the most unique places. The Tony Hawk Experience is your exclusive opportunity to have a personal experience with you and your friends with the world's most famous action sports figure and to benefit the Tony Hawk Foundation while you do it.”
This is Genius! Professional athletes and celebrities have been doing things like this for years. It is typically labeled under something foggy like "Guest Appearance," includes a hefty appearance fee, and is trafficked through their agent. But most people don't know about it or think of it. The brilliance behind what Tony Hawk is doing is that it is posted as a prominent link on his website. He is putting it right out in front of his audience! Hawk recognizes that fame is directly tied to having fans, and he is offering himself up to those fans in the places they spend the most time - the internet.
Tony Hawk's online popularity, augmented by the release of his 11th video game title, is evidenced by his more than 1.4 million Twitter followers, ranking him 24th most popular on the site. It is the old maxim of "Go Where Your Fans Are"

My favorite is this for $75,000 - “I will pick you up at LAX in my 620hp Jeep SRT and we will visit cliché tourist spots” around L.A. That's a bargain, folks. I would charge you at least twice that and I'd pick you up in a Honda Accord.
