just noticed that a lot of ads (Eros and others) for traveling providers have no mention of roses, donations or anything else.  If we can't talk about it when we call them, how can you know what to expect...or is there an upcharge?

Ask when you call, most will reply and tell you a range for their company. Also, read reviews and you can find out that way if they are well reviewed.

I thought you could not utter anything about an exchage of money, coins, flowers, IOUs or anything else such a "range" for services.  I thought they would hang up, or at the very least, phone conversations can be recorded.  what should be asked?  "How much does it cost for you spend time with me? each hour?
thanks in advance - all new to me

Well, every provider is different.  Some say "I don't talk about that on the phone, just be generous".  Others come right out and tell ya. I for one would not say "whats the rate...".  Maybe how many kisses or how many roses, etc.   This has been discussed in the past........

As a general rule, from experience and reading hundreds of reviews....Agency:  $350 +, Eros....250 - 300 (sometimes more), BP:  250ish, CL, 200ish, Paper...lower.  If I can't get a decent read on what they expect, I pass.

is to expect to pay $300 although i find the norm starting to come down towards $200.

Don't go by what the reviews say.  I got yelled at by thinking that $150 rate thats stated in some reviews were ok.  I find that most of the time if not always they will tell you how much it is right before you set the time.  What I despise is when they ask how much do you have or what you have for me.

$$ for most imho, $$$ only if great reviews or of my choosing because of past personal experience.  past that, i need to win the lotto.
