3 fully produced songs needed.

We have 3 scratch/demo tracks written with vocals for an EP and need a producer who can help us create commercially viable tunes. The songs are alt-indie in nature from 3-4 minutes each. We need recording, mixing, and mastering. Would like to start with one and see how we vibe. If all goes well then we'll produce the next two. Please quote a price for the above for 1 song and 3. We'd appreciate the production, recording, mixing, and mastering broken out as line items. Thank you in advance. Regards, David

Additional info:
I'm looking to hire a very experienced producer. I'd like you to also mix and master if possible. I need live instrumentation added. . I will be recording vocals on my own. I represent an artist. The lyrics and vocal melody are already written. I don't have a hard deadline for this. I need someone to help with the entire song-making process - writing, arrangement, creating background music/beat, other instrumentation, mixing and mastering.
