I'll be happy to take care of your editing. You will find that I am meticulous in my work. Nothing I edit is ever shared with anyone else. Confidentiality is part of the service.<br /><br />A 4K document would take 1-2 days. Yes, you may submit a sample. I encourage you to do that. I can offer you a 10% discount.<br /><br />I look forward to working with you.<br /><br />Best Regards,<br /><br />Nyanidoc
