Hello, I am a B.A. in English Language and Literature, pretty much in love with literature, and knowledge, in general. Psychology was one of my favorite subjects during my studies, and I have spent a lot of time reading psychologist and people who deal with psychological issues (Dalai Lama, Daniel Goleman). I do have an eye for detail, as I hear and correct grammar in my head as I hear it, usually from every speaker near me I pay attention to. It is sort of a defense mechanism, as I am a writer myself and would love to preserve complete control of my grammar. With that in mind, I might be a good candidate to proofread your book. As stated, it would take me five days, as I would love to do it in great detail, so not a single typo can escape into printing.
I do wish you the best of regards and hope to hear from you soon,
Milan. :)
