photography strikes me as a local business. in other words do you really care if someone in china knows about you? maybe if you are selling photography and can deliver it digitally sure.
but i am assuming you are refering to physically taking pictures at weddings/family portraits, graduation etc? if so then a good idea to get started marketing on the cheap might be to approach similar but non competing businesses in your local area. for example if you are specializing in wedding photography, you may want to visit the bridal store that sells dresses, or the wedding planner`s office and develop a relationship with them. they can then refer business to you as couples go to them to plan their weddings.
this is a free and instant solution for you initially. develop these relationships with as many vendors/service providers where your client is likely to go. start with your city then move outward to nearby cities. if you do well with this you may never have to spend a dime advertising. after all your income is a result of the hours you put in. there are only so many hours a day you can work. the business you get from word of mouth will be more than enough to keep you busy as you build this over time.
you can continue to evaluate your business development and growth as you move on - perhaps hire staff in the future? start a website and sell some of your work? photo auctions? ebay? the possibilities are endless.
good luck to you and let us know of your progress!!!
