Yeah I felt like a fraud too like when I marked prices for my products. They felt over-pricey to me too (like literally I never would've bought them at the price i put them at) besides they (customers) felt my products could actually help them (while I myself dint have any guarantee). But really, my friend just said. Put the price if someone wanna buy they will. Else not. That's it And guess what. People buy. And some come saying it was helpful thanks! While some not. It's part of establishing a business. Trust yourself. You will eventually feel what you're doing is worthwhile when you see the content faces of people :D.
