After several helpful discussions on the forum the printing side was solved;

Next we turn to a digital form. I realise there are several links here on 'how to' but was after some general info first.
Lightning Source have looked at the PDF and stated the book is considered a 'simple' conversion. It is mainly text, many photos, TOC, index etc but at 0.33 page to covert it comes out at $230. And then the same amount fot the MOBI conversion.
So maybe I should try to do it myself. Export the PDF to Epub.
Is it really that simple?, a one click job and does Indesign 6 do a better job than 5.5, 5 or 4?
How much tidying is generally needed?
Thanks
