Looking for someone to teach me how to play the guitar properly

Hi, I'm David and I'm 15 years old. I'm looking for someone who can help me or rather teach me how to play the guitar properly. At the moment I can only do a few riffs but I want to improve and I know it may even take me years but I'll take it. As far as I'm concerned, the person can be a girl, boy or whatever, as long as they really try to teach me and tell me whether I'm suitable for it or not.
