Thank you to everybody who has offered their assistance. I have been overwhelmed by both the quantity (and speed) of your kind responses.
Actually responding to you all individually would prove to be a major undertaking, so for most of you kind people it will have to be the form of a form email, for which I apologise.
Oh yes and of course, no further offers of assistance are required at this time. I am quite literally buried.
However if any more of my old associates who have acted as proofreaders for me in the past feel like they'd like to get in touch, I'll be only too happy to hear from them.
Best wishes
