epublishing for UK residents

Hi all,

I’m on the final (4th) draft of a novel written with Scrivener (won’t touch anything else now) and I’m keen to get it published electronically. It’s looking like a bit of a minefield. I’m planning on charging for it so there seem to be tax issues with iBooks (US tax number needed, etc.). I know I’ll need to get an ISBN too. Do any UK writers have any experience of this that they’d care to pass on?
