What research did you do that told you you will have carbonation after one week?
Are you bottle conditioning? If so one week is WAY too short, the 1-2-3 week plan for primary, secondary, and bottle conditioning gets thrown around here alot. But i generally wait a month to drink from my bottles. It makes for much more clear beer.
OR did you try to bottle force carbed beer? I've never done it, but i helped another brewer do it, and he kept his empty bottles in the freezer right up until he put the beer gun into them. He said this made a huge differrence in carbonation.
