This script stops you from moving, waits for a sec, and shoots.   
Works best with AWP, Scout can also be used.   
Copy&Paste script to autoexec.cfg located at steam\steamapps\name\counter-strike source\cstrike\cfg   

Code starts here:   

echo ""   
echo ""   
echo "AWP/Scout aim script succesfully loaded."   
echo ""   
echo ""   

alias awptoggle "awp_on"   

alias awp_off "bind mouse1 +attack;echo -=--=-AIM OFF-=--=--=-;alias awptoggle awp_on;fps_max 900"   
alias awp_on "bind mouse1 +shoot1;echo -=--=-AIM ON-=--=--=-;alias awptoggle awp_off;fps_max 61"   

alias w5 "wait;wait;wait;wait;wait"   
alias w10 "w5;w5"   
alias w25 "w10; w10; w5"   

alias +shoot1 "-forward;-back;-moveleft;-moveright;w25;w10;wait;wait;+attack"   
alias -shoot1 "w25;-attack;"   

bind F12 awptoggle   

Ends here.   

Copy&Paste everything between "Code starts here" and "Ends here"

EDIT: Now less waiting time! And every time you toggle script ON, the max fps is 60, which this script is designed into. When you press F12 again to toggle OFF, the fps_max is set to 900. WORKS SLOWLY UNDER 60 FPS
