Hi there!
Just came across your request for a proofreader/editor and I think I'm the perfect person for the task! While I am situated in the UK, I'm very familiar with American English (I recently completed an internship for an LA based company in which I had to proofread and produce development notes on movie scripts).
I'm new to this site, so I'm looking to impress and make a good name for myself, and I can therefore guarantee that the work will be done very quickly and to a high standard. Thanks for reading!
Regards,
Alex Wyse
