Feel free to contact me regarding Magento work. We've done a lot of custom consulting with Magento, including achieving over 75x speed increases in both Search and Import for very large Magento installations. Our largest Magento installation maintains between 2-5 million products from week to week.
We're also working with a few clients in a position very similar to yours. We're adept at coming into existing Magento installations to assess and fix problems.
