Maybe she is not getting your emails? She did respond to your posting on her business page.

If you have the message you sent her, I would copy it, go to her business page (yes it will be public, but what can you do? ) Say you've sent this twice with no response, but as she responded to you on the business site you know she is receiving those, and here is the request you sent along twice already. Be polite about it.

UNLESS you have a phone number, then I would say phone her first, before going 'public' with your request.
