I see that you are a 2-person "shop" - would you still have a "foo-consulting.com" personality if you were going solo? I'm kinda torn between the two.
On any portfolio site I've attempted to build, I really dislike using the word "I" (e.g. "I can help you build a website!").. but using "we" seems disingenuious. (e.g. "We can help you with your programming woes!").
Recently though, I'm leaning towards "we" because it's better business-speak, the "we" seems less risky, and it may not be factually incorrect if you ever outsource any work.
Generally, I tend to avoid writing copy that uses pronouns altogether.
