Well, in that case, it sounds like you had a pretty good stab at it - and if you received encouraging replies from the editors (ie, rejection slip 2) then it may well be that your writing is almost at the standard, just not quite.
I certainly appreciate the disruption and costs involved in moving house, but as before, my personal opinion is that if you can get an experienced editor to help you push the book to a new level that could mean acceptance, then that could be a worthwhile investment.
I sincerely hope you keep pushing on this once you've got a bit more settled - it sounds like you're beating most of the competition, so hopefully a bit more push could even get you published. Please do keep us informed on this.
