Copy 3 large WPMU sites to new VPS.

I have three Wordpress MultiUser sites set up at hosting company A and need them copied over to my new VPS and running properly. Properly as in what you see now. They are all three running fine as you will be able to verify so the job will not be completed (paid) until all three sites are running fine on my new Liquidweb VPS. The mysql databases range to as large as 1200mb. I will want to know how many transfers of large Wordpress MultiUser accounts you have competed successfully. I can do a simple one easy. These are a bit more complex but I have also been assured that it is all pretty straight forward. Naturally enough you get all of the passwords, etc.
