Yes, they need some guide it could be learn by books or by videos in Youtube. Everything can be learn now in this space nothing is impossible. But yes developing your capital for your business or project is kinda hard if you are doing it just for yourself. I knew it because I have an experience in that kind of thing before but I fail because I didn't took the risk and I limit myself.
I would suggest a professional in this matter rather than one's own self if they lack suitable experience. You can't just develop your own capital from thin air. You have to grow your money from what you already have, take loans from the banks if necessary or planned and then go public is the situation demands it and you have a high demand on the market.
This we can start from smaller ventures first, gain popularity through marketing and actually developing some that is useful then go for higher capital. It's a ful time job and no compromise should be made.
