Transfer scripts to mobi format for kindle / e-reader reader

I want to transfer documents from word or pdf into a mobi document to be read on a kindle / e-reader. This is a little more difficult than it sounds because because the document is not a novel or essay but a drama script so the formatting

Name: "Speech"
Name 2: "Speech"
stage directions / sound effects possibly in italics

needs to be preserved in an easy to read accessible format. I am attaching a small example of the sort of thing. This means that there may be some formatting of each document to do before loading up as a mobi doc. We are looking for a reflowable set of documents.

All told we will need about 50 scripts done - but we will be paying for the total job. I shall put in a fixed price but feel free to quote your own cost.

This needs to be ready for Sunday / Monday this week.

Thanks
