If your sole income is going to be from your photography business, then spend 8 hours on it. Half on client relations and business aspects then devote half of your work day to creating content that is unique and eye catching. Be active on facebook, instagram, twitter,youtube, and share the content you created.
If you dont put in the hours, you will probably not see that much results. But invest time and effort, and it will definitely yield you the results you look forward to.
And I assume you have a website already and branding covered as well. If you have not, then I suggest a comprehensive marketing plan to help you set the course early. Treat you busuiness seriously, and it will treat you good as well.
Think outside the box and go out of your way to create and brand fron the ground up.

Woohooo, that's a lot of words, sorry I got lost
