How to approach a somewhat, kinda, almost famous guy

I've had an idea for a while to try and bring someone who i personally think would excite the student body for once during a lecture. Instead of some older fellow that no one knows talking about god knows what. Why not bring someone in who students can relate to because he is not turning 60. Arya Toufanian is nearing 21 and has created a job that could potentially become his career. He was 16 when he wrote his fist book, Sex, Drugs, and High school. It was published while he was 16 because the publisher thought it would be a great idea to get a signing on someone so young. Before it was fully published his parents bought the book off of him and had it permanently destroyed. They were not fit to the idea of their name being on a book with such a name. With all the connections Arya had from his book deal he decided to move into the next level of his novel and start a company that focuses on what he believes is the key market for colleges, partying. His company, I'm Shmacked started small filming nightlife at colleges, and now he travels the country on a tour bus getting offers from fraternity's to just show up at their frat houses. I met Arya this summer in D.C where he used to attend school, G.W. with the success of his business he thought it best fit to drop out and see where this movement takes him. I didn't get too personal but he told me money was not a problem. He told me this was the first time he has been in D.C all year. He owns a house in Beverly Hills along with condos in other states. However, Arya is a cool dude, but contacting him, and trying to remind him who I was, was quite difficult. He gave me his number over the summer which was a drop phone because of all the people he meets. I texted him and told him how interested I was in having him come and do something he's never done before, lecture to younger students. Of all the things we talked about that night, luckily that was the one thing i remembered. He responded a couple hours later and remembered me somehow. He told me he was interested in coming to our school because thats an audience he's always wanted, high school students. Once I talk to administration i think theres a good chance this could pull through.
