I would call UKsugarbabes in London;

Black Angelica is in London @ the moment and touring Europe on a regular basis. As far as I know, they arrange international bookings with a minimum of 12 or 24 hours depending on the distance I think (travel costs extra). ...in this case it will cost you something around USD 2000.- (keep in mind: 12 hours!!!)

Also seen her in Vienna / Austria @ Terminpornbabes. - An exclusive hide-away where Pornstars (mainly from Hungary and Romania) check-in for a week. Always changing models including the big names from Europe. Maybe you get a better price there - try it!!!

Their Boss (Ivett) also should have all contacts and can surely arrange something for you; she is very nice and extremely congenial.
