Hello friends

I am planning to start up a business in Nigeria and try to gather all useful information before visit country.
Could you share your opinion about subjects below please?

- Do you think canned tuna and sardine products have chance in Nigeria (even neighborhood countries) with their long shelf life and high nutritive value?
- What kind of difficulties should be expected by a foreigner
- Same questions for Thai Jusmine rice and white rice grade-B

thanks lot
