Hi,
My name is Abigail, and while I'm new to Freelancer, I'm not new to editing. I have completed almost 400 orders on Fiverr and independently. I have an English degree from the University of Oxford and have worked for the Oxford English Dictionary, where I received training in grammar to an expert level. I also have high test scores in UK and US English here on Freelancer.
My CV is available on request, and there are samples of my work available on my profile.
I offer a two-stage edit. The first stage involves a copy-edit (rephrasing for wordiness, flow, jargon, generally improving the style), and proofreading (which corrects grammar, spelling, punctuation, and continuity issues). I use track changes to complete all edits, and deliver a tracked and clean copy. I can deliver in two stages, or do both edits and then deliver a finished manuscript, depending on your preference. Your payment schedule may make the latter option easier.
I expect that the edit of your novella should take ten hours, so at my hourly rate should stay within your budget. Factoring in my other work at the moment, I should be able to deliver in five days, and certainly by the 20th!
Please note, I don't do typesetting for Kindle books.
I hope this proposal works for you.
Thanks,
Abigail
