Headshot Sketches for Website & Presentations

I'm seeking an artist to create 5 - 6 headshot sketches in the same style of the example image attached. Photograph of subjects for sketching will be provided. The sketches will be used on a website and PowerPoint presentations, so they need to be professional and of high quality. Key Details: - Style: The headshot sketches should mirror the realistic, professional style of 'Natasha Mandie'. - Quantity: I need between 4 to 6 unique headshot sketches initially and will then add adhoc, as new people join our company. - Background: All sketches should have a transparent or no background, allowing for easy integration into various formats. Ideal Skills and Experience: - Proficiency in graphic design and sketching - Previous experience creating professional headshot sketches - Ability to deliver high quality, transparent-background images
