With this mindset I wouldn't advise you to start up a business, you need to change your mindset and approach towards business and how it's done, because there isn't any where that you make quick money except maybe at the Casinos, even at that the probability of winning is one to nil.
And you also talked about raising money, so you want to start making money but you can't source for capital, lol then you must be joking.
You need to raise money no matter how small to get your business off the ground and also make sure you do your research that the business you want to indulge in has demand, because you wouldn't make any sales or profits if there isn't demand for what you're selling.
If it's a local business then I suppose your target buyers are within your locality this will limit the funds you will use to start up.
If your business is online then you have to understand the market because you'll be competing with the whole world and to get a space you need to fight for it, if there's already a business that is using your own business model then you can see if there are lapses in their product and you can use that as your own selling point
Basically, it's all about thinking out of the box and making money in the process, looking forward to hear from you
