Combine Two MS Doc Files Into One & Format

We are combining two manuscripts for two books into one manuscript for one book, so need someone with excellent Microsoft Word experience to: + Merge both documents into one MS Word document (DOC file type) with book 1 preceding book 2 + Ensure that all the paragraph styles are set to “Body Text” + Some of the paragraphs are double-line spaced, so these will need to be converted to single-line spacing. The "Body Text" style includes separation space after each paragraph so double-line spacing is not needed. + Create a “Heading 0” style which is hierarchically above “Heading 1” for the two book's titles, so you can... + Create a new “Table-of-Contents” (TOC) at the front of the document (showing H0, H1, H2) and delete the individual TOC's at the front of each of the separate manuscripts + Heading 0 & Heading 1 should start on an 'odd page' (aka the right page) + Fix any obvious spelling problems and let us know about any obvious grammar problems + The header of each page on the combined manuscript should say which book the reader is on + The footer should just be the current page number + The page margins should be the same throughout the document Information about the documents: + Manuscript 1 is 219 pages, royal page size 15.6cm x 23.4cm, English Language (UK) + Manuscript 2 is 311 pages, royal page size 15.6cm x 23.4cm, English Language (UK) You'll need excellent Microsoft Word skills including: + Insert & Update a “Table of Contents” that is generated from the Heading styles throughout the documents + Know what a header & footer is + Understand what “Styles” are know how they work in MS Word I'm sorry if the above sounds obvious but we've hired a freelancer before who knew none of the above and was updating headers, footers and TOC by hand in a 300 page document. Ouch.
