Hello there! Glad to bid on ur project. How have you been? =)
Well... I have worked with computers for long time, and I will be really honest with you here, because I know you must be full of "blah blah blah, I am the best to do this job, blah blah blah". Insted of that, I preffer to be honest.
1) You have such a situation here. It's well known around the community that Cryptowall 3.0 is painful to remove, unless you pay the bad guys who created this malware the (painful) amount of US$ 500.00 (or US$ 1,000.00, if you take a long time to pay them). So, once your files are really important to you, they force you to do this.
2) What I can try to do for you is try to recover your files. But as you see, it's not guaranteed (I choose to be honest to you, remember? Please, consider this. I'm a professional, so I have professional attitudes). Removing CryptoWall is one thing. Recovering your files is another completely different one.
I'll leave my bid here. Hope we can make business and start doing something soon to try to recover your files! =)
Take good care, peace!
