Need Help - $$ for person that helps me solve

I have a Multibit bitcoin wallet that I forgot the password for. I believe that I know the pieces for the most part. it is something like 8chars 4numbers 4 numbers and same 8chars. Obviously it isn't that exactly or I would have already got in. each section is separated by 2 consecutive chars (like ##). I need to get access to this before the price of BTC drops, not a lot in there, but enough to make it worth a couple hundred to get someone to help me solve. I have a new box with 4th gen intel quad core and 2 MSI 270x GPU'sd (Crossfire) and 16gb ram, currently running windows 8.1. the wallet was created on a mac, but that shouldn't matter.

Anyone want to take a stab at it?
