What Affiliate Programs Actually Pay You?

I am legally disabled and I am searching for online methods of extra income. Can anyone recommend an affiliate program that actually pays on time,has been around a good while, and can be totally done sitting on my butt looking at the computer screen (well not that literal LOL!)?

I am planning on having a personal website and linking many businesses and services through their affiliate programs. Has anyone ever tried this? I only expect to make a very small amount of money, but I am curious.
