Hi Ahapea,
Join SSTV. It is a forum made especially for struggling singers like you, which I am a part of. There are five prominent experienced people who give out advice, I'm one of them. A good rule of thumb is to avoid taking voice classes in any type of academic environment. They usually teach you classical method, which basically turns you into a classical singer. Other times, it's Estill, which turns you into a musical theater singer. At SSTV, we'll help turn you into a contemporary singer, which you may actually be interested in. Don't worry, no catches, no strings attached.
Regards,
Kendrick
