I need images increasing in size for printing

I am seeking a skilled professional to enhance a substantial collection of images, increasing their file size from approximately 479 KB to between 5 MB and 10 MB for high-quality printing in a catalogue. This project involves approximately 1,200 images. As a preliminary test, please provide an enlarged version of the attached sample image to demonstrate your capability. It is essential that the final images retain clarity and detail suitable for print. Your expertise in image processing and enhancement techniques will be invaluable in achieving these requirements efficiently.
