Parsley seeds are indeed not the easiest to get to germinate but they'll do so eventually, like most of the umbellifers (parsnip, carrot etc.). The best time to sow is said to be when they'd normally fall from the plant - i.e. autumn - but failing that, make sure the soil is moist but not sodden, and not too cold. It would probably help to start them off indoors in small pots and then transplant. Two weeks is not too long to wait, and it might be longer.
Successional sowing is a good idea, but actually once they get going you can harvest a few leaves at a time and they'll keep growing. In the right conditions they can be rampant!
If you don't succeed, buy a potful from the supermarket in spring, separate out the dozens of plants therein and plant them. That's what I do!
