i think it's certainly possible to make your company's image look professional without all the corporate speak, buzzwords, and stock images.
my company is mostly just me (unless i sub out parts of a project) and i usually use "we" when talking to customers. many of them know the company is just me but they are already my customers. a potential customer might not even consider calling me in the first place if my website said i'm one guy. if they have a big project planned and they think it needs a whole team, would they even consider asking a one-person shop for an estimate? maybe not.
I think the choice of "we" versus "I" is bicycle shedding for copywriting. I've seen software developers paralyzed by this decision. (No, really. It used to come up with some regularity at the Business of Software boards.) They've both got merits -- pick whichever sounds good to you and get back to stuff which matters.
