Our very gray living room is in desperate need of artwork (and has been for a year!), but I'm stuck on how to find affordable art with such a large space to fill. For reference, the couch is 134.5" wide and the room extends beyond the couch on both sides. The teal lamps will go away so you can ignore those, and the teal pillows can obviously be replaced. Are we better off finding a single wide canvas, a series of canvases, a ledge with framed pieces on it, etc.? The cost of commissioned art and custom framing is high, so I'm trying to determine if there's a better option that won't cost $1,000+ and where to source it. We prefer contemporary art (for reference, the last photo shows a piece in our hearth room that I absolutely love...it's from a local artist).

Thanks in advance for your advice!
