Essays / Guys I'm stuck in my economic essay [8]

Hi all,

I'm writing an essay about economic differences between two countries
around 13-15 pages

there are so many things to write about this topic,
that I found its a big mess to organize them in order

could I get some help like how should I get them in order
such as starting from background to comparing their outcomes please,
so maybe I can get some ideas.

Also may I know is there any web site to learn how to make clear content please
( especially for over 10 pages please )
Regards
