I work primarily as a copy editor for translations.
Projects have included websites for several major banks, annual reports, press releases, CSR studies and fiction/non-fiction prose, amongst others. Due to copyright and my current employer I am not allowed to post examples of most of my work. Feel free to make a request privately, though.
I follow the AP Style Guide, US English. UK is personally preferable but less commonly requested.
Editting time taken per page ranges from 10 minutes to one hour depending on the standard and content/terminology of the text.
Proofing is generally quicker and obviously only includes facial errors and formatting inconsistencies.
Any requests/questions will be replied to promptly.
