But don't neglect the issue of money as you have pointed out. Or even better if they allow you to try a few 1-hour lessons, then a few 30-minute lessons, and see which one you prefer eventually. Voice classes are usually priced in increments of 30, 45 minutes and 60 minutes. Occasionally, classes are shorter or longer, but the vast majority are within the range of 30 to 60 minutes.
During our first 30-minute lesson together, my teacher was able to find ALL my vocal weaknesses and gave me exercises that immediately improved them. Many singers who go on tour consult a singing teacher daily for weeks before the tour, and communicate regularly with them during the tour, as well as for a set-up or to address issues that arose during a concert. As for private voice classes, Skype has done it so you don't have to take private voice classes near you. One of the best things I got from my first classes with a private singing teacher was a clear sense of direction to work towards.
You should always feel that the singing teacher cares about your interests and is offering good value. To keep things simple, I'd like to share some research I've done on how much singing lessons cost in Austin, TX. If you haven't had that opportunity, incorporating too much new information into a longer lesson will probably frustrate you more than help you. Or maybe you're doing something with a longer short-term learning curve, like ear training, where you have to practice it within the lesson and have the teacher check that you're doing well.
The best age to learn to sing depends less on physical maturity and more on factors such as self-motivation, available practice time and ability to concentrate.

But in Austin, there are so many singing teachers that it's hard to get an idea of how much singing lessons cost. Parents may need to help manage practice time, especially early on, when the student is new to singing.
Because singing does not depend on fine motor skills or the coordination involved in the use of other instruments, the best age to start singing classes varies from student to student. If you've been teaching private lessons for a while, you may have started with the 30-minute music class format. As with anything else, sometimes the more expensive the teacher is, the higher the quality of the voice lesson. The other reason it's important to find prices for singing lessons that fit your budget is that you want to make sure you can spend a certain amount of time developing your voice.
