I suggest you start a website and put only your best work on it.
As you improve, get rid of the ones that aren't up to the new standard.
Put only your best photos on social media.
People will refer you to their friends who surf (if they have any).
Offer to shoot promo photos for events at no charge, and make sure they credit/tag you somewhere when promoting the event with the image.
Get some business cards made, and you'll be noticed, and eventually paid.
For fun, I threw one of your pictures into Aperture and cropped off the not so interesting bits and tried to make the day look less dreary.
If you can consistently PP the images in an identifiable way, that helps as well.
