No, I don't charge.
My credentials: I have a university education, B.A. plus working toward a master's degree. Major was psychology.
My reasons for wanting to beta a book such as yours is that I love to read; I've been reading for 75 years. I've beta read and edited several books, including 3 from another AW writer, my brother's thriller, my husband's mainstream novel, several of my daughter's screen plays and her first novel - an adventure/thriller soon to be released, and my husband's second novel, historical/sci fi., yet to be titled, and my own narrative memoir, A Proper Study: Mending Karen.
I'm not a professional editor, but I've been told that my critiques are valuable, and my eyes are sharp for catching errors.
I have no problem with a reasonable amount of sex and the language of modern novels (i.e., the F word; I don't use it, but I can read it with equanimity.)
My final motive: I want someone who doesn't know me to beta my memoir. But before I ask for that, I want to give whatever expertise I can to other writers.
Turnaround time: I'll shoot for a week. Certainly not more than 2 weeks.
If you want to use me, please tell me the level of reading you want.
I'll tell you up front that I am constitutionally unable to let a misspelling or egregiously inappropriate phrasing or diction to pass. I also like to be able to comment on whether the characters are believable and developed well. Also, I’ll tell you up front that I'm better at the minutia than the whole.
However, if you don't want your MS marked up (I use MS Word to review manuscripts), I'll try to control myself.
Actually, I expect your MS is absolutely porfect, and uses only appropriate werds.
Let me know your pleasure.
Karen
