Create box with two images inside

Howdy,

On this page: http://skintherapystudio.com I would like to add a box (with background colour of #f6f6f6) to the right of the first paragraph of text. The box would contain the graphic & button that are currently at the bottom of the page. See attached image.

I have no idea how to do this as I've only done this in Visual Composer before, not in the WP editor.

Thanks in advance,
Casper
