Summit Presbyterian Church

Hello, I have a document of many pages divided into sections. I would like to export each section of the document to a pdf file. Files can be saved by assigning a number as a name.I have no programming experience on open office. Does anyone have any ideas? Please help. I didn't find the right solution from the Internet.
