Absolutely you've got potential! Anyone who is willing to spend the time to learn about photography, why not!
Photography is a very expensive career to get into. The cameras cost a lot of money to buy, they cost a lot of money to fix and you constantly have to upgrade with what's "in".
Photography is self directed career, there are very actual "in" buildings where you can go and work. It's all self directed career. You will have to build a portfolio, create a website. You will have to get in touch with the right contacts and you will to do a lot of word of mouth. It takes a long time to build up clients and you will have to do a lot of good, free work.
As long as you realize the expense and have the time and dedication, nothing can stop you from not doing it.
