Beware of this freelancer! He seems really great, but cancels mid project when he cannot complete it. He is quick to anger and be emotional. This has happened twice with the same freelancer for us. We asked him for a schedule for moving our servers from InMotion Hosting or OHV. He was supposed to migrate last week, and never did. Then he cancelled the project. Now we are stuck mid-transfer on a new server, and I must start from scratch.
