Difficult to vouch for this company not properly vetted.
IMO, get the Zaino kit and do it yourself. I trust one else when it comes to detailing my MINI, and would never use buffers.
Claying is easier than you think. Spritz surface with the wash lubricant and work the clay onto the wet surface area....My R53 is 6 years old, had all sorts of blemishes from stuff on the surface. One afternoon with the Zaino kit and my MINI's paint looks just as good if not better than it was when it came off the boat.......
