latex math text with custom layout

I have some text with math equations and a specific layout format that i would like you to build it in latex. I have it in a pdf format that i can send you to see and reproduce in latex exactly as it is. The text is in Greek. Every page has 1-2 images and 3-4 math equations. I can send you the texts and the images independently of the pdf. At the file attached you can see the page layout. Every page will have the same titles - subtitles format, but maybe slightly different boxes (bigger, smaller etc depending on the text). I remind you that every page it is already fully done in pdf, so i will send you the pdfs so you can see exactly the page and reproduce it as it is. The first part of the job is 10 pages.
