We have a similar entry hall so I feel your pain! We use one of those extension poel with the light bulb changing attachment. I think we did buy it at Home Depot or Home Base. However, we also need a ladder to get up high enough. I'm afraid it takes both in our case. Perhaps you can borrow a ladder from a neighbor so you don't have to buy one.
I don't even want to think about painting that area!!
