Need a single or possibly a EP mixed and/or produced

I'm looking for help mixing and producing a single or EP for my Electroclash group Nasty Mintz. We have some demos recorded and I do some engineering and producing myself but I'm looking to take it to the next level. We are a two piece and the vocal tracking I can do locally. The synths are mostly in the box and stripped down so they could use some help as well. We are big fans of Hot Chip and are in that ballpark. We could also use some guidance as to which songs to focus on. Please let me know what your rates would be for this service. Attached is one of our demos. Cheers, Nasty Mintz.

Additional info:
. I don't have a hard deadline for this. I'm an indie artist. I have a song already recorded and want some additional production elements - sound effects, synths, samples, percussion, re-recorded instruments. I'm going to hire a different mastering engineer. I need the mixer to do some editing, time aligning and vocal tuning before mixing. I'm looking to hire a top pro who's worked on hit songs, and have the budget for that.
