This is a freelance book editing and professional review website. It is monetized by Amazon Associates as well as by the services offered. It can easily be run one person and generate a few hundred dollars per month depending on the workload you are willing to take on. There are thousands of indie authors who are looking for help with book editing, getting reviews, and exposure for their titles so this is a rapidly growing niche. Currently I have set prices for service plans based on what I feel my time is worth, but what you charge is up to you. You won't have a shortage of customers with the right promotion efforts.
