how to set up my mask

hello,

i have 1 bet with a friend, to steal his password within 24 hours..
i know the following:

password is 12-20 characters long...
first 2 characters are numeric 00-50 00-50 then going one "!" character and then the rest is combination of alphanumeric upper-lowercase ... how to set up the mask for hashcat?

is this possible to crack this password within 24 hours?

PS: I know the hashcode of password of course..

thanks for mask suggestions
