If you can organize the costume yourself I'd be willing to bet most of the escorts would be more than willing to dress up for you, maybe give them a quick primer on how you'd like them to act too.
From what I hear most of them are very accommodating and will try to find a girl that is into that sort of roleplay for you too. They live on repeat customers and good word of mouth so they will try their best to make you happy.
I know JHGC is a big one with foreigners, they primarily employ girls that know at least a little bit of English and aren't actually all that expensive.
