proof-reading needed for eBook

Hi,

I'm looking for an experienced proof editor to proof-read and to edit my 7,000 words eBook. My budget is prorated rate of $10USD/7,000 words.

To apply, please send me your previous work samples — preferably with a "before editing" and "after editing" — or a document with "tracked changes" turned on, so I can evaluate your editing skills before hiring you.

Thank you.
