Haircut

Perhaps I simply don’t make my wishes clear—although I do provide various pictures from several angles—or am too provincial in my quest for service—although I have gone to numerous outlets on the advice of many individuals—but I find it impossible to get a barber/stylist/salon…person to give me a decent haircut. I think I shall be satisfied if one, just one, of these so-called trained professionals can grasp the concept of “when my hair is dry it must naturally reach here (hand gesture to the appropriate spot along with pointing to the pictures mentioned earlier)” and have them cut my hair so that is within a few inches of that length. What should I expect for $50?
