Hi Lorna. We don't really have the concept of business pages in the same way as Facebook. At least, not at the moment.
Do you perhaps mean a business profile that you can use to comment as your business? If so, you'll need to log out and then create another account. Perhaps named "Ls_Boudoir" - you can then use the logo as your profile picture and put details and a link to your website in the bio.
We'd ask that you only use this business profile to respond to members' questions about your business. If you'd like to start new topics about L's Boudoir there is a small fee for each topic.
