I need multiple x1 images photoshopped onto the same background

I am looking to launch an online shop to sell my artwork digitally. As part of setting up my storefront, I require approximately 100 individual artwork images to be professionally composited together into a single large collage-style design. Each piece should be sensitively incorporated into a harmonious layout utilizing a common background theme to help cohesively promote my full product catalog.

Skill with Adobe Photoshop is essential to seamlessly blend the various artworks into an aesthetically-pleasing single digital file. Creativity is also important to generate an intriguing visual that will catch customers' eyes. The final product should resemble the sample image I have attached but composed of my custom collection of artwork. Clean lines and tasteful framing elements will help establish a high-quality brand image for my store.

Attention to detail is needed throughout the process, from carefully matching color palettes between pieces to maintaining consistently-sized frames. Upon completion, the finished digital collage file should be professionally tailored for optimum online display at high-resolution without risk of pixelation or other digital artifacts. This project offers an opportunity for an experienced graphic designer to showcase their skills in constructing an impactful showcase of my products for an upcoming online launch.
