A friend started that type of business in my country a few years ago (end covid): she is pretty successful and I gave her a chance for a trip I am on now. It mostly exposed how absolutely terrible everyone seems to be at this: she did absolutely lazy work I could have done fast(er) and better myself (usually do and will do again), but, seeing her other clients, including a friend, it seems most people are just really bad at it, far worse than she is (or wants to spend time on I guess).
