Sound effect related Q

yeah, I post it here!

it’s a design-wise question…

the thing is, I need a specific sound effect.

an effect like… a sewer lid hitting a metal floor and bouncing once, just a tad…

and maybe when it hits the first time, a little groundshaking bass to add to the effect…

I tried the Sound Forge demo, and to be honest, I’m a total d****ick with it… :sure:

I just need someone to nudge me in the right direction =)

(I even tried google’ing it, just came up with lousy effects and “free” CD’s… psch… yeah right…
