I need help with my weapon script

[Loganawe]

So I do not know if any of you know about flappy fedora and my friends and I thought it was really funny so I decided to make a weapon in gmod about it. It works but not as we want it to. There is a few things we want help with.

1. The sound does not work, I recorded a clip from the game and it just goes like "tip", I made sure that the bit rate was fine and the size and everything but when I try to use it it makes no sound, I am not sure what to do to make the sound work.

2. We want to use this as a real gun, we want a shotgun that does like 25 damage and it shoots fedora's. These are the model's
models/player/items/spy/spy_cardhat.mdl
models/player/items/spy/spy_gang_cap.mdl
We want ether one or both of them (right and left click)

3. Also we use this: models/weapons/v_shot_m3super90.mdl for the model but it's left handed?

4. If you guys can give you some tips on how to do this or just fix it for me. The sound file is called tip.wav, and I think the main thing is I do not know where I put it.

Thanks

If you want somebody to help you at least put it in the proper format.
I'm not even going to attempt to fix this for you.
