Hi, my name is Matt and I believe I can help you (22 years of webmastering experience).
If the code - after some analysis - is crypted using only CryptoJS (free, open source javascripty encryption library) then it can be done e.g. there is no key to break, only analyze and decrypt code back - looks like only Base64 encoding is used - and try to rename functions to more meaningful names (as they are renamed too).
If we start to communicate, it would be best to try a simple test first before you accept this (and actually any) bid.
Looking forward to your reply,
Matt
