Hi Belle_of_the_Ball!
Welcome to DanceScape and wonderful to hear about your interest in Dancing!
The best place to start is probably to see if there is a local USABDA chapter (United States Ballroom Dance Association, or now known as USA Dance - see
http://www.usabda.org). If you speak to a representative, they may be able to direct you to local dance studios or clubs in your area that offer lessons. BTW, in which City/State are you located?
If you are interested in trying out lessons but not quite ready for "private" ones ... try "GROUP" lessons. They are generally lower cost and if you start out in Beginners, you can "sample" dances. You might love them all, or you might love certain styles (like Latin versus Ballroom, etc.)
Private lessons are more expensive than group, but you get more personal attention. It is also possible to tailor your lesson to certain dances.
One thing about Ballroom is that it is a "team" dance and you will need a partner at some point especially if you decide to go into competition dancing. It does tend to take a little longer to find a male partner as dedicated as you might be. However, there are competitions called "Pro Am" where it is possible to compete with your dance instructor.
Some dance clubs have "singles" only dances so it might be possible to begin networking, depending on your age.
Hope this helps and if you have any other questions, please feel free to post. Try also
