Typically, in a prose novel, you would describe the brochure, not reproduce it.
After patiently listening to my story, she pulled out a resort brochure titled Transformation Intensive Programme, and pointing out with the pen in her hand she said; “Here, this one looks like something interesting for you."
It cost £1500!
It would be possible to include it as an illustration, but that would be unusual. Children's novels are often illustrated, adult's novels occasionally are, and there are some novelty books that heavily feature graphics. Unless you're serving as your own illustrator, however, those details would be left to the illustrator. In any case, it would definitely be premature to focus in on them now.
Occasionally, a writer will use a hybrid technique, as in your example, of suggesting a menu or a pamphlet or other printed object through typesetting, or occasionally boxing it off. There is no standard way of doing this, and the way you have of indicating it in your manuscript is fine. If you want to go further you can add notes to the editor in square brackets. That's probably not recommended however, unless it's absolutely essential. You can always discuss it with your editor after you have a deal in hand.
