I just recently quit being a professional photographer. I have several keywords such as "city photographer" on page one and on google places. Trust me, they don't start calling all at once. If they do, all they do is canvas for the cheapest bastard. On a couple of occasions, I had a studio. That even did not do it. Sure they came but the consumers are just retarded. One guy came in my studio, talked to him about things he needed. At the end, he asked me how much. I gave him a discounted price. He said "I thought it was $5 per print". I showed him the door.
Trust me, there is no money in wedding or portrait (any type). Not unless you want to get paid $500-1000 per wedding (after calculating your hourly - probably end up being at $7-10 an hour after the hours spent). It's super saturated with everyone with a DSLR! It will put you into debt buying pro equipment.
If you REALLY want to go into photography, do something that NO ONE is doing. Make sure you learn about marketing and business since photography skills is just half of it.
Lastly, the most frustrating part was finding who was REALLY interested in professional photography services. That's the hard part.
Good Luck!
