Kinda 0.T... php site and maintenance

Hey, Got a question for you guys who make a lot of personal sites. I got a US client who wants me to make a personal site, 4-7 "sections" (eg: about me, photos, whats new etc) and have to put a yearly maintenance $$ amount... I thought i'll make most of the stuff using php rather than plain html so the client can update different sections without me (eg: whats new, add pics) What do you guys charge for something like this (dont count hosting and domain fees) Thanks!
