you can start with
./crunch 10 10 ABCDEFG0123456789
which will generate a 2.1TB file (17 ^ 10)
However you said you don't want 1111111111, 1111111112, etc so I would add -p before the charset and see if that is more to your liking. The -p option will generate permutations instead of combinations. However it will generate 17 character long words which probably is not what you want. You might as well just use:
./crunch 10 10 ABCDEFG0123456789 and be certain that every combination is checked.
I am also close to releasing a new version of crunch that has support for specifying the locations of character, numbers, and symbols in the pattern. So if you know that the password is in the format of char, char, num, num, char, sym, num you can use:
./crunch 7 7 -t @@$$@^$ ABCDEFG 0123456789 \!\@\#\$\% (yes you need the forward slashes to escape the sequence)
