Pages, Posts, and Categories

I have 3 static pages and 1 blog post page where all my posts go to.

I want to add a 4th static page entitled “Beautycounter” for a company that I have joined as a consultant and I know how to do that.

My question is: How do I do blog posts about Beautycounter and get them to post to my blog posts page AND the Beautycounter page? I blog about other things than Beautycounter so I want everything to post to my blog post page but the time when I post about Beautycounter to also be listed under the Beautycounter page. That way people that are just interested in my Beautycounter business can click on that page for posts regarding that only. I’ve set up a category for it put each Beautycounter post in that category so that can search that as well.

Am I thinking about this correctly? Or should I just have a static Beautycounter page that tells about my business and hyperlinks to my shop page (www.Beautycounter.com/KarenChason) AND to the categories page?

Thanks for your assistance.
