Hello!
I am a native English speaker and writer from the United States. I will do a detailed proofread of your projects. I'm a little unclear if this proposal is for just one short project, or more than that. Assuming it's the former, I bid $15 to polish it up for you. My thorough proofreading includes a detailed look at spelling, punctuation, grammar, alignment and formatting, case, spacing, and word usage. I will also make suggestions for minor sentence structure revision and rephrasing for improved readability, consistency, flow, and clarity.
I have done the test doc you attached, but I'm unclear how to send it to you. If you reply to me, I'll send it immediately.
Please give me a try, you won't be disappointed!
