Bottom line is that without a website these days it's hard to get your work out there in front of the market that you need to be seen in. Sure there are websites that you can join and upload your images to but those sites are flooded with thousands if not tens of thousands of other creative people and in order to found on those sites you have to pay a premium.
Creatives are a special breed and need to focus on their work. Most dont have the time to build and mange a website let alone all the techy stuff that goes with it.
Thats where I come in. I am an artist myself and I know what's needed to get not only my work in front of my own audience but others as well.
