Of course you can, it's just a computer after all. The real question is, will you? To answer that question, you will need a trial period. You can elect to hire yourself or a member of your secretarial staff as your webmaster and, after a few months, evaluate the experience. In the mean time, however, your site will be live and viewed by potential clients. So it would be wise to have a professional webmaster at your immediate disposal via a retainer fee. This allows you to ensure your site will stay up-to-date (whether you or your staff follow through or not) at minimal cost.
