It's okay - but I bet you're right. I think the liking, etc. is more related to an individual account (never mind that with a business page, you can act as if you were the page, and like posts, reach out to people, etc.). It's certainly worth a shot.
BTW - I'd suggest associating this individual account with a Gmail account and then associating the site itself with her individual Google profile and Gmail account. Why? Because she should become a Google Verified author
. This performs a neat trick whereby, sometimes (and Google never really tells you when it will/won't do this, but I imagine that's proprietary knowledge) Google will associate her Google profile image with its search results for her page.
