Looking for a Native US Proofreader

I am seeking for a Native US Proofreader to help us with our ongoing projects. The project includes proofreading website content, ads, descriptions, posts, and packaging. The initial document is under 1000 words, and it contains keywords that must remain unchanged. We require a prompt turnaround. The ideal candidate should have excellent proofreading skills and be a native US English speaker. Experience in proofreading is a must.
