Help Sha1 hash cracking

[mdka]

Hi guys !
I wonder if someone can help me crack these two sha 1 hashes
--hash-removed-by-atom--
--hash-removed-by-atom--
most likely the chraset is mix-alpha numeric with length in the range of 6 to 10 characters,most probably 7-8
I had tried with various techniques - pure bruteforce - too long,dictionary attacks,combined dictionary,rainbow tables - no result
10x!
