Any advice on hand sewing for a newbie? Sewing Machines Parts and Sales in Los Angeles

I want to start a business selling clothing and I have a wonderful idea for clothing styles, and would like to also make and sell plushies and bags, but I’ve got barely any experience and no sewing machine (or money for one). Ironically my only experience is on my friends sewing machine when they gave me a lesson. Does anyone know where I can find detailed lessons for hand sewing? I prefer instructions given through image rather than text, so that’s a definite bonus. Also, if you have any advice to give, it’s definitely welcome.
