Different countries different situations. If you lived here which you dont. You could learn all you wanted to for a small weakly outlay. You could also like some here who compete in three different styles of dancing and have two lessons a week on each style. That gets really expensive. So with Latin it can be taught and practised in a reletively small area. If it were at all possible I would find say three other people and share a lesson, which is what I did. If you could find a room at school that you could use you might be able to engage a suitable instructor privately. My experience in this matter. I arranged an hours lesson once a week . There were three of us. Because the teacher is currently placed in the top 30 Professionaly in the Standard Style they are away for weeks at a time as they are at this point in time. From wherever they are, I think it is in Hong Kong they will then make their way to Europe for more training and then to Blackpool. To get to the story. One of our class was terribly slow at picking things up. I came to the conclusion that I would be better off if I had a lesson on my own but every three or four weeks which would cost no more than the once a week job, and I learnt so much more. So if you do go the way I suggested pick your other class mates well.
In parting don't drink, don't smoke buy your cloths from the Salvation Army.And don't start selling body parts , you'll need them. Good luck.
