Good Morning from USA! It's appropriate when you talk about a place. If a person asks you about your shop or in your case maybe your Carpentry company or services. Person: I am looking for a Carpenter or I am looking for Carpentry services. You: "I am a skilled Carpenter." "You have come to the right place!"

thanks a lot for your explanation!

You could use it referring to yourself (or another person) if you were in the place where you use the relevant skill. E.g. if you are a carpenter and someone came to your workshop looking for a carpenter, then yes, you could say "I am a skilled carpenter, you have come to the right place," even though you are talking about yourself (person) rather than your workshop (place). On the other hand, if you were in a place where you wouldn't normally use your skills, you wouldn't say it even if on one occasion your skills would come in useful. For example, this would be a very strange usage of the term: SCENE: RESTAURANT Man: Aaaah! Oh the pain! Woman: Help! My husband is having a heart attack! Is anyone here a doctor? Doctor: I am a doctor. You have come to the right place. The doctor in this example is using the expression very strangely. It's only a coincidence that the doctor is present and can use his skills to save the man. If the doctor were not present, the man would not be in the right place. The right place, of course, would be a hospital. As a side note, the doctor could say afterward, "I was in the right place at the right time." This would express the happy coincidence of him being present to help somebody who definitely wasn't in the right place to experience a medical emergency.
