Taking 2 lessons a week at $100 per lesson is $800 per month. 3 lessons a week costs $1200 per month. This comes out to $9,600 or $14,400 per year.
If you are an amateur this is a major expense, especially if you begin using visiting judges, or you travel to take world class lessons in NY, England, or other locations. If you are really trying to get competitive you could easily spend $25,000 to $35,000 per year or more. Some higher end competitive coachs could charge $200 per hour--depending on if they travel to you or you bear the expense of traveling to them. One needs a sponsor, trust fund, or money to pay for all of this. You need this coaching to even have the judges look at you. Look at how much (millions) the Chinese Pro AM lady was paying for lessons. A guy that was the American Amateur Smooth-Rhythm champion for years had independent money. He would fly in world class coachs from Italy, England or wherever. Bet he spent $75,000 or more a year on coaching.
Still there is no guarantee that you will win anything. Yeah it helps if you have some talent, but you also need lots of money for world class lessons to even throw you hat in the ring. Even someone with some or little talent that has money for years of high quality lessons will eventually become competitive. They will eventually take from all the judges and will become recognized if they are very persistant and hang in there for years. Sometimes it's partner stability, money,hard work and staying power. David and Valentino will probably be the next Am. Smooth champions. They have been competing and paying for these high end lessons for maybe 8 years.
