The business idea you have given may be fine but I can give you a new business idea.  If you are financially sound then you can start a filling station business. I have seen many people I know succeed in this business. As the price of fuel increases, people will need it and no matter how many filling stations there are in your area, you will have customers at every filling station, so if a company wants to employ you as a dealer, you can take this business.

I have this kind of business plan from long time but I don't have enough money that's why I can't start this business.  I will definitely start a filling station business when I have enough money to do this business.

I just gave you this business idea considering the context of your country if you think this business can bring you profit then you can do this business.
