yucky
since that is the way you feel about the trade, it is probably best if you don't get into it. no matter how beautiful you are, that attitude would show through in your sessions, and no one would be satisfied. you know what they say, most important is to find work you enjoy, because you will be good at it, and the money will follow. nothing worse than dragging yourself to a job you hate or loathe every day.
without a doubt if you are beautiful you can get takers at 4-500. its a trade off, lower vol and higher price. to make the maximum dollars, i believe the sweet spot is in the $$ area, and that is why its where the market has generally settled. and less like at the spansh houses is considered dirt cheap but there is a limit in the girls capacity so even with unlimited customers avail they cannot reach peak earnings. and volume means a lot of hard work. at the other end, $400+ will mean many fewer clients, a lot less work. perhaps a couple a day? at $1k rates at an agency, a few a week? maximal dollars earned per unit of work, but not the most absolute dollars you could have earned. in the $$ range, expect 5-10 clients per day. it seems that most working girls like that balance; not too much physical work to do day in and out, but enough to stay busy so not bored. and the $ per add up quickly. where you want to fall in the amount of work/amount of return spectrum is entirely up to you.
some girls work for an agency just long enough to build up a clientele they want going forward. guys they are comfortable with and don't feel so much of that "yucky" factor. that they know more or less so the security and marketing aspect is not so daunting. then they go independent, keeps the house's share and give the guys a small break on the rate. this model works for a lot, but it take effort to setup. personally when i find a fav, i would love to cut out the middleman and see her outside for a somewhat reduced rate. it's also more personal. win-win for all but the previous agency. but they get their share of coin as the agent initially matching the buyers and sellers.
best of luck to you, in whatever your decide
