I like to have a small business, privately owned, no matter partnerships or sole
Is there a particular area you like to have the small business? Retail? Food? Professional services?
yes i am interested in food industry, I would love to own a restaurant 
That's so neat. Would you want say a cafe - coffee in the morning, sandwiches and such for lunch? Or would you rather a full dine-in experience with a certain type of food?
I like a fast food restaurant, like packaged form for take-out/take-away. but healthy one
Interesting, I have only seen a handful of  those around that be a great niche to get into.  What would one of your dishes be?
I would like have a healthy salad dish, precooked but not frozen and still healthy to take away
That be nice. Especially for people on the go who would like a healthy alternative to a greasy burger.
yes like Olivier salad, which is popular  in old Soviet Union countries
I have never heard of Olivier salad. I will have to look that up.
