In my humble opinion $400 is too much. Heck even $300 is too much tbh. $250 should be the cap. I haven't hired in the US for almost 2 years now. I take trips to Barcelona or Brazil etc. (I understand that the cost is more in total) but I get more bang for my buck.
I am no stingy person. But the reason I do not agree with these prices is because we talking about RM here. I can only speak from my experience, majority are not outclass, excellent providers. We are talking 400/HOUR here. You can only do the deed and leave. There is no "experience" so to speak.
Now I understand someone who is pornstar material or is one can probably charge that but not just anybody.
I really like someone here mentioned that high cost does not equate with high equality in this industry. This is so true!!
It is slowly become rare to find a provider that is excellent quality, some want money upfront, cut the time short, do not follow what agreed upon etc. etc.
