That fulltime salary is a rounding error for most companies, especially when you consider that you need that person anyways. Seriously, I'm making a large part of my living off companies that once thought (or were told) that they could do without a sysadmin. If the internet-part of your business consists of more than a static website (or a wordpress) then, by all means, pay that fulltime salary. Even if you decide to go fully managed hosting; you absolutely want that to be an educated decision rather than an educated guess. And it doesn't end there. A never-ending chain of small decisions is waiting on every step of the road. Pull that knowledge inhouse (or to a trusted longterm advisor) as early as you can. Otherwise you will inevitably foot a much higher bill later in the game.
