Spine surgery

Ash • 💋
I'm sorry if this is irrelevant to this group, it's the closest one I could find that may answer my question.
I'm a 15 year old and I have scoliosis it's when your spine is either Minorly or majorly curved. It bothers me everyday, when I bend over or sit on the floor my back starts to ache, it feels like hell. 
I've been thinking of dropping out of year 10 probably in July so I can get a full time job to pay for the cost of my spine surgery.
 Anyway my actual question is :  How much is spinal surgery, I know it's not cheap.  Anyone know?? Xx
