Need painting of a concrete floor in small workshop

I'm looking for a reliable person to paint a concrete floor in my small workshop. The area is about 25 square meters and currently bare concrete. I’d like a durable epoxy or polyurethane coating suitable for light workshop use and easy to clean. Please include surface preparation (cleaning, grinding, priming), two-coat application, and a final seal. I prefer a neutral grey color, but I’m open to a sample first. Access is straightforward, and I can provide paint and primer if needed, or you can supply materials. I’m aiming for a tidy finish with minimal downtime and a quick drying time.
