[P] image comparison

I’m building an AI agent for a furniture business where customers can send a photo of a sofa and ask if we have that design. The system should compare the customer’s image against our catalog of about 500 product images (SKUs), find visually similar items, and return the closest matches or say if none are available.

I’m looking for the best image model or something production-ready, fast, and easy to deploy for an SMB later. Should I use models like CLIP or cloud vision APIs, and do I need a vector database for only -500 images, or is there a simpler architecture for image similarity search at this scale??? Any simple way I can do ?
