Roy boy, you have many great suggestions to choose from. The electric snowmobile gloves/mitts would be my choice, one size larger than needed if you want to also use a glove.
There are simple things to do to improve your circulation. Niacin, a member of the vitamin B family will cause your blood vessels to open and increase circulation. However there is a price, niacin causes flushing and tingling until you get accustomed to it. Start slowly with a daily low dose and build from there, best taken with meals. There is a NO-flush form of Niacin but I cannot say if it is effective for circulation.
Like everything else, use your head and don not over do.
Here are some links that can better explain.
