Is $3,700 to paint two floors of a townhouse a fair price?

My boyfriend and I are new homeowners and don't know what we're doing. We hired painters recommended by a neighbor because we wanted everything done before family visits in a couple of weeks, and we didn't get additional quotes. We provided the paint, initially guessing the quantity, and ended up needing many more gallons than anticipated. I was frustrated by the painters constantly asking for more paint after I'd already asked if enough was on hand. We also experienced a language barrier. I'm very non-confrontational and regret not demanding a re-do or discount. We just bought this house and wanted to make it our own, and now I feel like crying because we can't afford to have it re-done professionally. I'm pretty sure these guys don't have an actual business or license. I'm in MD and my house is about 1300 sqft. I have physical limitations, including bad tremors in my hands, which make physical labor challenging, so fixing the sloppy work myself will be difficult and slow. I had intended for the bedroom trim and doors to be color-drenched in teal, but they were painted blue, clashing with the walls and ceiling. I've learned a lot from this experience about what to look for in a contractor and paint quality. I've decided to move on and try to fix the issues myself, starting with the hardwood floors and then the paint, even though it will be a slow process due to my health.
