Their a great agency and the owner is an OG in the industry in all respects. You can be direct and transparent with her about what it is you're looking for.
I haven't engaged with the agency in the last 6 months or so, but I do know a few of the girls in the group personally and yes business seems to be going steady.
Yes, in the past they have been transparent about offering fs through the agency itself...I don't imagine that's changed recently.
Best bet is just to reach out to them directly and ask which girls are available for whichever services you're looking for. In my experience EE doesn't have a problem sharing info & details with you. Their business is largely based around transparency and easy booking.
