Google Apps Email Migration from one Google Apps account to the other

I am looking to migrate thousands of emails from one gmail apps over to a new gmail apps account. I have the instructions but I'd rather leave this task to a Google Apps or migration professional with years of experience. I have enough storage on the new account and would prefer is the emails were automatically deleted from the old account as they transfer across to the new account.

Requirements:

- Able to come on-site to setup the transfer
- A good knowledge of email migration
- Experienced in Google Apps
- Reliable, trustworthy and professional
- Affordable as it's a personal project

I look forward to hearing from you.
