Warlord Games to a modern survivors plastic kit as part of their Project Z game, and these have all sorts of heads, hairstyles, and modern clothing that you can mix-and-match. You may have to add a 'stache or glasses to get the head you want, or maybe file the top of a head to get a balding look, but they are pretty cheap and might let you do a number of other friends/co-workers too (note that they also do a separate female survivors kit as well).
