Have you ever shot interiors before? What is your approach going to be ... ambient only, on camera flash, off camera / studio lighting? Delivering SOOC or color correcting for mixed lighting @ window/artificial/falloff?
Concerns over licensing to infinity & beyond are one aspect of your pricing structure. So is "work for hire". Others are the amount of time that you'll be putting into the project and the level of workmanship that you'll be delivering.
As mentioned ... you need a more defined scope of work. You can get that by asking the client ... OR ... you can suggest to the client what it is that you are going to recommend / provide and the accompanying pricing structure for that delivery. Then ... if the client wants something else, they can always ask to modify it. I find that if you are asking them what they want (when they really don't know), it sends a message that you may not be the "expert" after all ... and that thought has a way of diminishing your value in both their mind and yours.
The client gets what the client wants, but I don't tell my doctor how to perform the procedure, just that I want it done. If the doctor were to ask me how I'd like it done ... well, you get the gist. I'm not saying that you should be "bull headed" about doing it your way ... just be sure and have a game plan going in. If you are relying on the client (some have good thoughts, some are clueless) to have a strategy at what they want, you may find yourself in a challenging situation to deliver something you're not prepared for.
If you're familiar with the "storyboard" concept, you can present that either in draft, sketch or verbal form. They'll either follow your lead or provide some feedback from that baseline ... but either way it shows you've come prepared as knowing your mission ... which adds value to you.
If you're only providing walk around snaps (which may be what she's thinking), then your pricing will likely reflect that. If you are providing more than that then you may have a challenge to value the work differently than she may be thinking. In the end, it will be "what the market will bear" ... but as you get more "scope" info lined out, the way to approach the $$$ will become more clear.
