Loud humming noise, possibly a wheel bearing?

Hello. At that age and mileage, a wheel bearing is very likely the issue. If you can get someone to ride with you, have theme sit in the passenger seat so they can feel vibration in the floor. They should feel the vibration changing with the speed of the car and sound. Also, being that the noise is coming from the right side, when you go around a curve to the right, the noise should quiet down some until you straighten out again. Also, it should get a little louder when you go around a curve to the left.

You might also have them sit in the back to make sure that the sound isn't coming from the rear.

I'm including some screenshots of AllDatas instructions on removing and replacing the hub. Generally, I recommend replacing the hub assembly and not just the bearing. By the time you pay a machinist to press the new beating into the old hub, you've spent as much money as you would have if you just bought the whole hub. You can get guns pretty cheaply from Amazon. I've had no trouble with Detroit Axle brand parts, so that's probably what I'd buy.
