for a casual acquaintance, why do you need to to use an alias?  You seem overly paranoid.  Is this hobby really for you?

The sugar bowl is a good alternative for those that have the time and the patience for it that is.

 
BTW what do you consider the "VIP-level" provider? Some might consider that the $400 hr girls, other guys might think of VIP level as a grand an hour. What kind of price tag equates to VIP-level in your book?

in LA   VIP starts at $700 //  on other markets its  $400  

besides why cant you just use the Search parameters of TER ..   its very easy.   speaking of VIP .. you have to have a TER VIP membership to do that ...  if you don't .. get one ...  don't expect others to do your work for you and save you money while you don't support this site.

Tell your casual acquaintance I said this, pass it on. How they use to say? Play it forward... or was it pay it, whatever.

if you have VIP status you can search for providers in your price range.

 
or you could contact the those VIP-level provides that you can't afford and ask if their mom is still working.
