to be honest, then i have no ideas really where to head at...
but i once was at somfthing called siteground.com, greate service tho, and still... its inside USA, i think... they was last time i checked ^^'...
in anyway, could recommend them and some few others,
but the best (where i feel safe), would be this site:
http://www.feralhosting.com/features
they are designed for hosting of torrent sites, and trust me when im saying they are big, they are big than bigger...
one of my friends have a torrent site with (almost) over 20.000 people on it, and same shit with torrents, but still... i said almost ;)....
besides,... he has been running it for over almost 3-5 year now, (dont remember the exact years..).
but a little warning if you should by yourself in there...
my friend tryed to install tbdev source in there.
and it was with a socked since they dont use localhost in there for some idiot reason, in anyway... it was keep telling my friend some errors that he could not fix... so he had to change service orr torrent source, so he chossed the source...
hope it helped :P...
