Add Footnotes to Book Manuscript

I'm seeking assistance to add more than 300 footnotes to my book manuscript about the Vietnam War written in Apple Pages. I have all the references. Just not skilled at EndNote and the Mac plug-in. Plus factchecking the quotes while adding in the footnotes and adding a Bibliography...
