If you want to be sure it's done in 2 weeks or less and will taste good for sure sooner then later once bottled, then you should always
1) Ferment in the yeasts sweet spot (which is often warmer then a lot of Americans try to push their yeasts to avoid flavor)...
Note that you probably do not have this problem unless your basement is 62 or < and you are fermenting there.
2) You need to pitch a lot more yeast then you get with a brew demon/mr. beer kit.
Most of my beers are actually done fermenting in 3-7 days, but I pitch at rates found here.

You are pitching half as much or even less then I do if you are using the provided yeast packs depending on the recipe/kit.
Even if you do start pitching at those rates, If I were you, I'd still leave it in the fermenter for 2 weeks, good things happen during that extra week that will give you better beer sooner once you bottle it. Basically the yeast remove compounds that lead to "off flavors".
How much this matters to you depends on your taste threshold for such things and what things are produced during your fermentation.
IE, I *could* bottle many of my beers at 1 week from a "it's done" standpoint if I wanted to, but typically I don't, because I taste something called "acetaldehyde" (green apple flavors) at very low thresholds, and don't want to taste ANY out of the fermenter before I bottle. Because more gets made bottle priming, and there is less yeast in the bottle to clean it up in the bottle, so "extra" going in is highly unwanted. It cleans up much faster in the fermenter then it does in the bottle at any significant concentration.
FWIW, the yeasts provided by Mr. Beer/Brew Demon throw off a lot of acetaldehyde if you ferment too cool, I basically hate those yeasts fermented any lower then 64 degrees, they are best at 64-68 (active fermentation temperature, not ambient room temperature).
Some people might not notice the flavor. But they still might get a headache from it if they drink too much before it's gone.
