Sha1(user:pass) decryption

[deepsylol]

Hello guys.
I just found out how awesome hashcat is and now I'm trying to figure out how to decrypt these passwords:

The passwords are generated this way:

Code:

$hash = sha1(strtoupper($user).':'.strtoupper($pass));

I know the hashes and the user name and I'm looking for the password.
Can anyone help me to configure hashcat, so I can decode these passwords?
Thanks.
