I notice that you are 70, so you should be on Medicare which pays for IVIG under Part B and you have a 20% co-pay. If you have supplemental insurance, the will pay the 20% and you pay zero. I don't know your financial situation, but if at all possible, my recommendation is that you try to have supplemental insurance so you don't have to worry about the cost of your treatment.

As far as IVIG in southern VA, if you do a search under Google, you should be able to locate an infusion center. All infusion centers do IVIG because it is used for many other types of illnesses than just mg. I was traveling in central VA last year and found an infusion center about a mile from sister's house and had no problems because I made the appointment before I even left home and had my doctor fax the orders directly to the infusion center.

Good luck!
