Hmm, I don't know. It's certainly possible. I find the comments rather disturbing, I must admit, after all the work I have put into it. I really have no idea what she means by comma use and 'dialogue tags.' That's a new one on me, but I'm not a copy editor per se.

Personally, I have no trouble knowing who is talking in the dialogue. 

What sort of price are they quoting you? I really don't think you should invest a lot more money in this, as I have a feeling that it is literally going to be a case of 'polishing' that doesn't add much to the quality and readability of what you have already.

I think it would also be a good idea to ask Patti if she is familiar with these folks and get her feedback if she is. I wouldn't be surprised if she knows of them.

In the end, it is up to you, of course. Do let me know what you decide and if you elect to hire them, whether you are pleased with their work.

All best,
