I think I'll take my sabbatical in Fall of '12, so I am available for speaking engagements and workshops during that period of time. I can either talk about my research, or lead a workshop on scholarly writing along the the lines of SMT, or do both. Invite me and I am likely to come. You'll have to pay my expenses, travel, hotel, and meals, and pay me a reasonable honorarium. I don't have a fixed price; it kind of depends on what the balance of intrinsic motivation to extrinsic is. (If you invite me to Paris, you don't have to pay me much. Omaha, a bit more.) We are talking about the range of $500-$1000.
