Sure a great website is good. But its no use if you cant market it properly. So here are some ideas that can get you started.
1. Start locally. Visit/email/call local photography studios who would have a use for your services. Offer them to see examples of your work and what you can offer them.
2. If you own your own designs or photos, you can try offering them for sale as prints on places such as etsy, ebay etc.
3. Build a website, can be as simple as ordering a script such as photography orders, or having one custom made for you with a sweet design. Once you have a website the entire world is at your disposal. Network with photographers, and businesses who offer products that can benefit from your service. Maybe you can provide a better rate, dropship etc.
With a website you can also toy with adwords, facebook ads, twitter, advertising directly on websites that already capture your target audience etc.
Best of luck.
