Compile Information Into Several Ebooks For Me

I have 22 folders with varying amounts of txt files in each one - anywhere from 10 to about 22 or so. All the text files are short - usually less than a page of text. I need all the txt files from each folder to be compiled together into an ebook with a table of contents at the front. The table of contents would simply be the title of each article or text file. So, in the end I would have 22 ebooks with the information inside. There is no editing or additional work to do done. The files would actually be sent back to me in a word document so I could tweak them a little before creating the ebooks. I hope that's clear! Please let me know if you have any additional questions. Thanks for looking!
