She is grateful for their help! Unfortunately, it sounds like locating services without any local help will be somewhat difficult.
She'll check the indicated locations for student housing, thank you, hopefully there will be a few large dorms that she can at least use as a price/quality reference for other locations (because she suspects students may be some amount of noisy to live next to, or even rowdy, although she's willing to be pleasantly surprised). She can always stay in the Lodge for a few more nights while she finds a good place.
She definitely doesn't need a whole house! Not unless she settles here for the long term, and even then an apartment in a well-run building might be better. Interviewing and hiring staff will be inconvenient, buying and selling it will presumably have transaction costs as well as paperwork, and the whole thing will end up more expensive than just eating out and paying for a laundry service.
She is very disappointed to hear Osirion does not have public libraries! (In the sense that anyone can pay to walk in and read any book they want, and possibly check them out, although making them free for residents is also an excellent use of public funds.) Libraries let you look through many books quickly until you find the ones you need. Shops make you buy the wrong book, or buy a lot of books and then resell them after a week, and don't stock nearly as many books to choose from. ...fine, Tanya will visit some bookshops. She hopes they stock a Golarion for Dummies series.
Tanya has a lot of experience in hiring (and also firing) people! From when she used to fire people only metaphorically, that is, before the army. But, well, she isn't local. Putting out an ad sounds reasonable, she's not calibrated on the base salary and conditions to mention in the ad itself but she'll, uh, buy a newspaper and go from there, the worst that can happen is that she'll waste a bit of time interviewing.
She thanks the teller for their help and goes in search of a clothes market. Can she find something in her size that handles the heat better and, importantly, also handles rapid aerial maneuvers? That means staying in place if she happens to be upside down and so on. She can do her own shade so a hood isn't strictly necessary. And of course she needs a lot of pockets. ...really, her current uniform is great, it's just that it was meant for overflying the Alps. If local fashion isn't meant for flying she's prepared to order it custom made out of the right kind of fabric; there should be a tailor in a secondhand clothes marketplace somewhere. What fabrics are used around here?
