Kalla switching back and forth between first and third person speech is partly because the offer to buy her took her by surprise and partly because consistency is for drow, or other people who cares about such trifling matters. Shinies do not!

Because relic hunters that aren't part of a clan or guild often are poor (that's why they go relic hunting, hoping to make it big) I had the Nal'sarkoth be practical and include non-ada methods of payments, including bartering and services.
As far as I know, the Tei'kaliath do have some ada and you could probably pay for some relic hunter packages. However, if you want to be frugal there are other methods of payment available.
The ones listed are 'or' options btw, you don't have to do all of them at once.
As for the fanservice it sort of comes natural. They are all adults with (presumably) working libidos and as far as I know not body shy. Certainly the Nal'sarkoth are not. It's not that they have sex at the drop of a hat (not even the Sullissin'rune*) but sex has more of a social recreational activity aspect among drow than it does for humans IRL and I tend to write them accordingly.
Should your character be asexual, or monogamous/polygamous restricted (that is, in an exclusive relationship) just send me a note and I'll keep it in mind when writing scripts. If not, consider your character free game.

There won't be any actual sex (that's Daydream's prerogative) but there will most likely be hints and teasing sometimes, like in this page (and yes, that clerk was totally checking out Minalia's neck.

The 3% cut of any finds is a bit of a gamble since the relic hunters might not find much (or even come back at all; the mortality rate is substantial) but it might also bring in a significant sum. The Nal'sarkoth do have people doing relic evaluation at several of their outposts as well as Chel itself. The method has so far turned a slight profit, so it's continued.
The Tei'kaliath who partied too hard did not get pass-out drunk on wine, it was the chocolate that knocked them out - eventually. The Nal'sarkoth actually paid for most of it, since the party was a nice morale boost for the outpost and they got some useful information out of it.
*Well, most Sullissin'rune wouldn't. Maybe some would, you never know.
