I'm writing non-fiction and after a fairly lengthy e-mail conversation a publisher asked me to do a full proposal for them. I sent the proposal over six weeks ago and have heard nothing.
I haven't been in the non-fiction world before so I'm not sure how long to leave it until I bother the publishers about this. As part of the proposal I had to give a date for completion, as time goes on that date gets more unrealistic (it was fairly unrealstic in the first place!).
Anyone have any experience of this? Should I have heard something by now or is August just a bad time? And how closely do non-fiction publishers expect you to stick to an initial deadline? I'd be grateful for any advice.
