Hi, I would like to offer my proofreading/editing services as I am an editor by profession, having worked with the Editorial Services department of SPI Technologies (one of the world's largest BPOs).
I have edited hundreds of pages of articles written by not only non-native English speakers but also by native English-speaking professionals all over the world. These cannot go to print without a thorough editing/proofreading check via my department. I have reviewed articles over a wide range of fields (Engineering, Science, Finance, IT, Medicine, and many others), and once these have been meticulously edited, publishing giants such as Springer-Verlag, Elsevier, Taylor & Francis, etc. are ready to accept them.
My editing work includes checking for spelling, punctuation, grammar, correct usage, simple formatting, syntax, and flow. By the way, do you mean a Service Level (as opposed to 'Layer' in the bid request) Agreement?
Ready to start upon bid acceptance and escrow of milestone.
Thanks and regards,
Angie
