need help with 555 delay timer



What I need is a simple circuit for a 5-10 second delay. No voltage
for 5-10 seconds, and then turn on and stay on. I've googled this, and
simulated the circuits that people have designed for this purpose, and
they don't seem to work. I know someone who tried actually making the
circuit and it still didn't work, so I think my simulation is correct.
Can anyone help?
