Without seeing your portfolio, no one can really say too much that's definitive.
So what genre are you looking to shoot? What sort of portfolio do you have, and do you have a site set up to show it to others? What can you offer that people can't find with other photographers in your area?
And in the end, why do you want to make it a business?
Making money with photography is more about business skills than ability as a photographer. If you're interested in the business aspect, focus on that. If you're not, and just want to shoot for the joy of shooting, why ruin it with the stress of running a business? If it's more of a need for money, there are far easier and more reliable ways to get a paycheck. If you just want a bit of extra income from something you enjoy doing, then just have fun with it, charge a fair price for shoots when people ask, and don't expect too much if you aren't actively marketing.
