I am in Richmond but I'm afraid I can't help out much, unfortunately. I am in the medical field so I don't have much knowledge about your line of work, but I can tell you that the cost of living in the New Kent Co. area is going to be lower than what it is in Richmond proper, but higher in the Williamsburg proper area. You are not going to have to pay a grand for an apartment, I am sure of that.
What about Siemens/Motorola White Oak Semiconductor? In terms of large manufacturing companies we have Philip Morris and Tyson chicken, and Nabisco.
When I moved back to VA (hometown) from years in FL, my bank actually was the most helpful in my relocation, helping me set up a mover, finding an apartment and storage when I got here.
