What a mysterious world the provision of domination and fetish services is. It may be an area you'd consider exploring if you have an interest in certain kinks. Sometimes it's a service that occasionally sex workers branch out into when they are wanting to go beyond full service sex work for one reason or another. However, being a dominatrix is much, much more than the odd spank with a paddle, encompassing psychological components and sometimes delving deeply into the past of a client and storming into their psyches, occasionally into a dark place.
Just about every full service sex worker I know has had the same old guys doing the rounds, calling or texting them offering to be their house slaves. That would be fine, but they are usually very poor cleaners, and to add insult to injury, they expect to have their fantasies of being dominated and humiliated (that is, crawling around in the nude cleaning our loos) indulged for free or in exchange for "cleaning."
It sounds all very temptingly easy, but there are dangers involved with domming.
