i m expert by work but not getting orders guide me what i have to do
You apparently have professional training as a medical caregiver, but you’re trying to sell logos here on Fiverr? I’ve looked at your logo design gig, and it does NOT look like you are an expert. Buyers tend to purchase logos from sellers who can prove their experience, skills, and client experience. You don’t have any of that.
Perhaps you might find better success as a seller if you offer services that you are ACTUALLY an expert in.
