Need advice, starting paver cleaning business

[anttlandscape 14]

If someone could help me out with advice on a good overall package needed to pursue paver cleaning. A setup with enough psi and gpm . Also the best brand of washer , what type of drive, engine, where to buy. And ill be washing driveways in the 800sqft to 1500sqft range - what brand and what size flat work washer would be best? I currently install in NY and would like to start to maintain as well. Side jobs will also be pursued, dont want to buy something i have to upgrade but dont need something over the top either. Sorry needing so much info but i know very little in this area. Thank you for any help on this.
