Once upon a time I finished college with a bachelor's degree in history. My dad kicked my backside into going to law school, but that is another story. And law school is certainly one option if you have a four year degree.
But here are the others:
Museum curator. If I were you I would contact every big city museum in the country to see what the job market looks like. And the reason I say big city is that just about every big city museum is close to a metro or subway station, which solves your lack of driving problem.
Reenactor. Contact the folks at Gettysburg, Williamsburg, VA and any other large historical site and see if they have any need for full time on site guides or reenactors.
There are also a lot of historical ships, airplane museums, and other such places that need folks with historical knowledge. You can also try amusement parks such as Knott's Berry Farm that use historically costumed actors.
Junior high or high school teacher. I do not know what your problem with elementary education was, but this is what I was planning on when my father pressured me into going to law school. You will need a four year degree and a teaching credential, but at least you get to teach history all the time, you get summers off, and the salaries are pretty good these days.
Book editor. You can freelance or work for a publisher, but you are going to need a degree in history or English or Literature, and some really good reading and writing skills.
There are a few other things I could have done when I finished college back in the 1980's but have been eliminated by technology, such as document coder.
And that is pretty much the list, AFAIK.
Now if you are looking for the easiest ways to make a LOT of money, there are two:
1. Welder. I have known a lot of welders in my day, and they never ever go hungry. There is always work somewhere in the world and it always pays high. Maybe in 40 years they will have robots to do all the welding, but for now welding remains the job that requires the least knowledge and pays the highest.
2. Selling real estate. Like George Foreman said, "If you can sell, you can eat." When you are paid by commission, you want to sell the most expensive things possible, and real estate is it. Take the classes, get your license, and learn how to talk to people and how to tell a real buyer from a lookieloo.
