Realistic Oil Painting of Couple

I'm looking for an artist to create a realistic portrait of a couple using oil paints. The painting should capture the essence and emotions of the individuals, with attention to detail and a high level of craftsmanship. Experience in creating lifelike oil portraits and working with couple compositions is highly desirable, and ability to use color and texture in the background (can be more abstract or realistic) is an extra bonus. Please provide samples of your previous work and let me know your estimated timeline for completion.
