The sort of pilot license you want depends on how much it will cost you to get it. For instance, a private pilot license will be less expensive than a commercial pilot license since almost all pilots must first obtain a private pilot license before applying for their commercial license, and the number of flight hours is also substantially fewer.  However, a private pilot license can be obtained for between $10,000 and $20,000, while a commercial pilot license can be purchased for between $25,000 and $35,000 on average.
