Yes you can. Say we/us instead of I/me for everything. I know there's one of you, and I know you're proud of that. But if I'm a client, fear of lone wolf syndrome may lead me to avoid your company.
Just imagine how I'll feel if he says we/us on his site and then I discover in our introductory call that he is a loner. Only say "we" if you can justify it. If you tell me you're networked and have a working relationship with ux/designers/programmers maybe that will fly.
