Need 3 songs mixed and mastered

I need 3 songs (approximately 3 minute) songs mixed and mastered for a professional sound. The songs feature computerized strings, reverbed drums and was created on Logic Pro. I am very happy with the finished product, minus some very minor arrangement adjustments, but I want to create space in my choruses. There are too many sounds fighting with each other. My biggest concern is the back and forth communication with the engineer. I need to have someone will be able to accept feedback to adjustments and really be willing to provide me with the sound I am looking for, not necessarily theirs.
