In some ways - an SPs rate dictates the kind of client she wants to attract. That doesn't mean that all gents willing to pay higher rates are better or even nicer, it is just less likely that she will attract the kind of guys that make this business hard. In the US - I raised my rates to be just above the average, just like I do here, because the lower rates I was charging attracted less suitable company for myself.
Is this work? Yes and no... for me, the work part is the screening, the website, the pics (well, not anymore), emails, phone calls, socializing, networking, etc... Meeting is not work at all, because by the time I meet with someone, I already am familliar with them, I already know them somewhat and am able to fully relax and enjoy.
Consider that for every 1st time booking, I have probably "worked" at least 2 days on everything from communicating with him, with his references, researching his handle, his email, his telephone number (in a dangerous client database - and keep in mind this is a US thing), and finally, meeting for coffee to establish whether or not we will meet in private. Moreover, sometimes this "work" bears no fruit - there are alot of guys who are time-wasters.
