Any tips for mixed InDesign file and PDF for cellphone mobile

[SebastiaoV]

Hi!
I need to create a book for an Architects' Conference due in 3 days, and it would be nice if it looked good on mobile phones. The problem is that I can create the 10-page Table of Contents in InDesign, but I already have an A4 PDF for the rest, which is also 1,500 pages. I don't have time to design the interior in InDesign; I have to use it as is. The Table of Contents will have links to the internal articles.

How do I combine the two files? Is this possible? I'd like to at least make the Table of Contents look good on mobile phones or adapt it to the size, but I don't know if that can be done in PDF format. Can I design the Index or Table of Contents with Liquid Layout? Epub is not universal to all people in the Conference so it is not an alternative. 

I know this is a lot of information, and maybe I'm not entirely clear about it. Sorry, English isn't my first language. 

Perhaps there are other options,  that I do not have in mind. Any ideas, tips, or options? Anything would be very welcome. 

Thanks 1000! 😉

To look good on a smartphone screen means usually making a EPUB.

A step lower would be a PDF. 

But 1500+ pages inside of 3 days? That is highly unreasonable.

But you could design the Table of Contents pages in InDesign; export to PDF; then combine the 2 PDFs together, and then build some Bookmarks from the front ToC pages to the major articles. 

A 1500 page anything is going to be an unwieldy large document to put on a smartphone. 

Why not tell them no?
