Is a good way to open a online store to sell the vegatables, fruits?

its a bad idea. see these things are items that can get rotten. you can never satisfy a customer. well if they pick the vegetebles by there own at a supermarket they cant blame anyone. but if you are picking the fruits for then and in case its not good they will naturally blame you

CHOOSE ONE OF THE EXISTING MAKE MONEY ONLINE SCHEMES ON THE NET

It will not be a good idea, my opinion.
If you really want to do something of this nature, where you can provide some service through net. Or make a service oriented site. That will be more better.Look arround and think which services you want from net, even at times on paying. List them. Prioritize them all. Now think, which all are feasible for you. At the same time, think which one matches with your local knowledge service and local sources.

Think in this line...........

Its just my suggestion, friend.

Thank you.

rather than selling straigh up fruits and vegetables why dont you sell goods such as cakes and sweets that you make from your fruits and vegetables. these are easier to distribute and there is more demand for them online. Also you can make them to order so they are always fresh and you can let your customers choose different ingredients to their own taste.
