Two answers: a) you can tell them it will be $10 a month for hosting, and offer to set it up for them with their credit card, or the client can make their own hosting account and host it themselves. b) You can chage up front for a year of hosting, then let them know you'll be contacting them in a year for another year of hosting. I would suggest a) is the better one. I tried to do b), but then got lazy/too many clients/hosting costs were negligible anyway, and now a bunch of my clients just get free hosting.
