I want to add a page to the footer, please help

My English and my knowledge of WordPress are a little limited…
I’m trying to find the best solution for my issue, but nothing is simple…

I have the Visual Composer, and I created a page… now I want to add this page to the footer, the whole page, not a simple link… if I copy the code of this page and I put it in the footer works perfect, the problem is each time a need to change the footer info, I need to make the changes in the page, copy the whole code and put it again in the footer…

I hope someone can understand me…

thank you very much
