Black Background & B/W Filter

I have a single photo that I’d like polished: please replace the existing backdrop with a clean, solid black and then apply a classic black-and-white filter so the subject stands out crisply. No other alterations are required... (Budget: ₹600 - ₹1500 INR, Jobs: Background Removal, Graphic Design, Illustrator, Image Analysis, Image Processing, Logo Design, Photo Editing, Photoshop)
