So many people have good ideas, but many factors have made them not invest in them to make them beneficial to society and profitable to the developer. Some people don't want to start small. They want to have all the necessary material, financial and other resources before they start developing their ideas. You don't need to wait to get all the necessary resources before you start and nurture your idea. If you can get funding from an individual or organization, that's good. But if you don't have such support, start with what you have.
Like the people op mentioned what they have developed and the things we know them for, I don't think they it wad project that they were able to go in with just small amount of money. Their are some Ideas people have and looking to establish it is jot just project you can start with Small amount of money. I know it is good to start something small with amount of money you have at hand. But their are some ideas koney is s limitation ro start, if you don't have the amount of money you want their is nothing you can do about to get it done.
