If you are sure of the frame size, buy it online. Prowl around Youtube for clips about how to do some basic servicing, and look at some more clips about doing the bike fit yourself. Unless you are hell-bent on shaving milliseconds off your time as a professional racer, bike fitting isn't rocket science, it's just a matter of comfort.
Good bike fitting isn't a question of shaving off miliseconds, but of getting a genuinely comfortable and efficient riding position, which works for you as an individual. Nothing online can tell you what is working for you, no advice can replicate having a professional watching you live. If you don't go for bike fitting, fine, but unless you've experienced a good bike fit, I'd suggest you don't pass expert judgement and say what it is or isn't. Maybe it leads to less slow motion? ;-)
