Need EP mixed and mastered

We've planned to record our first EP coming December. The recorded material will be available start January. The EP will be 4 songs consisting of drums (MIDI recorded on e drums with ezdrummer), bass and vocals (think Royal Blood or Death from Above 1979). We'll also record dry did for bass and doubles and harmonies for vocals, but all in all we won't have too many tracks per song. I'm looking for a engineer/company to take care of the mixing and mastering and optionally slight pitch correction on the vocals.

Additional info:
The song has somewhere between 10 and 30 tracks recorded that need mixing. I'm hoping to find a good mixer that can work with my limited budget. . I need the vocals tuned as well. I'll need you to master it too if possible. I don't have a hard deadline for this.
