Of course it is valuable, but why limit the choices a priori? Let your clients choose by themselves, maybe some of them will prefer to sacrifice face-to-face meetings in exchange for finding the best candidate...
In general, with marketing, you need to keep your Message simple. As in drop-dead simple. Especially when you're veyr small.
That's why you see food trucks offering tacos, sushi, or organic chocolate-and-truffle-oil-suffused hempseed brownies, respectively... but food trucks offering all 3 of these, not so often.
With recruiting it's kind of the same. Also, out-of-towners have different filtering / recommendation / communication needs, and take different payscales, also
So they're probably just applying the 80-20 rule, and catering to what their known client base seems to ask for most.
