Hi
In my experience, there are several ways to tackle this.
1. The immediate problem
You say you originally set up under your corporate name, so if your message comes from your corporate FB page you don't have a branding issue. I'm guessing therefore that your worry is that you don't want your fan to discover that your corporate page has little activity and few FB friends?
The way round this, in my view, is to generate activity on your main FB page ASAP. Bear in mind that your fans will find this page anyway: you can't hide it from them as it must appear in the fans list and will be a magnet to anyone trying to find out more about your business (which they surely will, if they're genuine fans).
So
(1) get as much info and so on as you can onto your main FB page: duplicate stuff from your fan page.
(2) Put out friend requests from this page to all 100 of your fans. Hopefully many will accept the requests within a day or two and suddenly you'll have a respectable following. Bear in mind that in order to send a message to the fan in question, you'll have to make them a friend anyway. By doing it this way, you'll have much more flexibility for the future.
(3) If you want a different FB entity to contact the fans, start a new FB account with all the right naming/branding and then make it an administrator of the fan page. Then you'll have a choice of which identity to write from.
OR
Message the fan via the general messaging options (e.g. using Fans' update - which you can make town/city specific - or the status update or wall) asking him/her to contact you via ordinary email.
2. The wider question
I'm slightly confused what is the best way to use fb to professionally market your business.
I'm not convinced that an anonymous 'corporate' page with only corporate naming/branding is the right way to market profesionally on FB. Social media work much, much better for business if you personalise your presence and build up your profile as a real person with a real identity and real life, representing the company. Social media marketing relies on trust and, most importantly, relationships, not just on a corporate presence. (The same, I'd argue, is true here on UKBF.)
Compare it to attending a business networking event. As you move about the room, meeting new potential customers, do you introduce yourself only by your company name ("Hello, John, my name's Actuarial" ...) or do you give your own name? Do you hide your face behind a mask (I mean a literal one!) consisting of your company logo, or do you let people see your own face, and get human responses by smiling at them, shaking their hand, laughing at their jokes, sharing an anecdote .....?
See where I'm going? If that's how you'd network in real social life, that's how you should do it in social media. Pretty much the same rules apply in building relationships and trust. As a very old saying goes, we all do business with people, not things.
So in your shoes, I'd create a personal FB page (not necessarily a
really personal one - you can keep back some privacy - but one with your real name and real photo etc.) and administer the corporate fan page from there. Personally, I think you'll find that much more productive.
Hope all this helps.
