Best way to convert 50 pages of EPS to AI?

[vixler]

Hi,

I designed a Wire-O spiralbound book in InDesign. Because it's spiral bound, it's 50 pages (that's total, front and back). The client had initially told me to send it in InDesign but now they want me to convert it to AI. The artwork in the book is raster, CMYK. 

What is the best way for me to do this? I have converted it as PDF to EPS so far. I need to not mess up the raster art. I would prefer it all to come out in one file, like a multipage AI file, but it's OK if it's 50 separate files, just annoying.

I could download Illustrator but I also see a lot of free online converters, do any of those work OK, does anyone know?

Is there a protocol to send files to create a book (again, it is spiral bound, so the pages are all separate)--such as do I include the bleed marks, slug, etc.? The client knows nothing so I cannot ask. 

Thanks!
