Hello Lila,
It's great you want to learn to dance! But, unfortunately, in order for this type of message to have a chance to succeed, you have to provide at least a general idea of where you live! And even then, I'm afraid your chances of connecting with a person in your area is is small.
You also don't say if you're a beginner when it comes to ballroom, or if you have experience in another type of dancing -- say ballet, for instance. Have you checked what is really available in your own area? Many colleges, and even high schools in some areas, offer dance classes that are MUCH more affordable than those from private studios. And even if you have no money at all, approaching the teacher of such a course with your work-for-lessons would seem (to me at least) be more likely to work than a similar offer to a studio instructor (the instructor makes his living this way, and needs to eat; the "continuing education" teacher at a college or school is more likely to be doing it as a part-time thing, more for "love" than money, IMHO). And a local offer to someone in your community is probably a lot safer than one on the Internet....
Good Luck!
Ralph
