As long as it's not ecommerce, shared hosting should be good enough.

In my opinion, the only difference, in terms of privacy and security between dedicated and shared is that shared can viewed by the people who work for the hosting company a little easier... which doesn't piss me off really to be honest. anyway, i would botch dedicated hosting if it was left to me. I'd rather leave it to the people who know.

Of course, if you had a good amount of clients, then dedicated or even VPS would be a much cheaper option... also bare in mind, support, etc.
