Since you receive lots of proposals - I will keep mine concise.
I own a seasonal company - during my off season I freelance the work that I do, which includes cover letters, PDFs, website writing, etc.
I am native to America, I am fluent and studied English in college.
I believe in open communications with clients, as well as proofs, agreements, and all common business etiquette.
If awarded the job, you can expect to receive professional, quality, and prompt delivery of your documents. Feel free to ask any other questions. Thank you for your consideration.
