One important thing to consider here is how technical the person you'll be dealing with (marketing guy or sysadmin), and whether or not they are actually able to make the decission (1st line support almost certainly can't).

So long as the request reaches a 2nd or 3rd line techie who can accurately appraise that what you're doing won't require too much work on their part, or place undue load on their servers, I'd be very suprised if they weren't responsive -- especially as they're a fairly small business.
