I have two sites, normal video & photography services and a separate sports video website. It is kind of a blessing and a curse. The ability to separate your services and clearly state what you do is great. What I do not like is people often not knowing what else you do. A sports video client might also need business or live event video, but they know my company as the sports company. My business cards have a company per side but it often does not translate. But it is a necessary evil as too much info/choices will result in overload.
