Recover single page deleted

Hello, I deleted a long time ago a page that I thought I wouldn’t need, but now I do.

I would like to recover a single page from the demo, this one.

Portfolio Simple – 2 Columns

Actually If I could recover all portfolio examples that would be great, so I could fool around with one or another in my website

However I don’t know how, my website developmente knowledge is very low.

this is my website;
