need 4 songs mixed and mastered for EP

I'm needing 4 alternative rock songs mixed and mastered for my bands EP. The songs are in a similar style to Foo Fighters and 30 Seconds to Mars. We'd be needing the 4 songs done in about a month from us sending them to you. The tracks vary between MIDI and audio files, and there's a fair amount of tracks for each song. We are a young, unsigned band so we don't have a large budget for these services, but would be willing to pay more than the stated budget here if we are happy with your work. Our band name is Cold California, if you would like to check out a few tracks then search ColdCaliforniaMusic on youtube. Thanks, looking forward to working with you!
