I'm writing this because there is one. Right now I've got space for doing assessments, if anyone wants one done urgently. That is, within the next couple of weeks.
These days I do a fast and effective assessment on an emailed attachment Word doc (which, for my sins, has to be earlier than Word 7 because I can't read docx annoyingly). As I read through, I put in comment balloons, so you can see exactly where the problem is in the text. Then I write an email assessment with general comments and details referring to specific comments as needed.
This system seems to be popular because it's quicker - and cheaper! Takes less time, so I can keep costs down.

And just to keep your hopes up, here's a quote from Patrick Dennis on his Auntie Mame (which later was made into a film) - "It circulated for five years, through the halls of fifteen publishers, and finally ended up with Vanguard Press, which, as you can see, is rather deep into the alphabet." Motto: Never give up.
