I am new with LaTeX code... Few months ago my mentor recommended me LyX and I found it funny to write my thesis on it.

I read some preview questions and did not find what I exactly want.

My issues:

1. I would like that the page number starts at the 6th page.

2. From the 6th page to the 50th page, I wanna add header and footer:

• header [L] {Analyse du mécanisme de compensation}
• header [R] a logo located in my document files PATH: C:\Users\M. Louis\Documents\New Scotia.png
• footer[L] {Mozard LOUIS}
• Footer [R] {Econometrics and Data Science, 2020}

With the orange line on it (see the picture).
