how many pages must be created in this catalog is the same as the pages of Word file?

It might be more, it might be less, as long as all the text is included and is fully legible
thanks for your questions. I hope this helps

I believe all the content and photos from word document will go to illustrator file and the layout will be like illustrator file only.
On the first page will the image from word file will replace the one in illustrator file?
Thanks

yes

May I know what about to the template design? Should I follow exactly the one in Adobe Illustrator that you've attached or we can re-design it?
Beside that, any color that you'll prefer or same as what I can see from the Adobe Illustrator?

Thank you.

Follow the template but feel free to redesign

Color should be the same from Adobe illustrator
