Hello

My advice is this


Convert your money to CFas and relocate to Benin Republic

Or Bakassi Peninsula


They are both abroad, and you can readily relocate back to Nigeria

But travelling with your family with no contacts whatsoever in the UK and hoping to float a business
successfully

Is like


Going to the river to fetch water with no buckets.

my sister which kind of business are you planning for, in a foreign land.

It's not advisable to relocate to a country where you don't have any contact to start a business unless if you have ur money in billions and ready to waste some because a lot of things involved

1)the type of business you want to start
2)do you have ur business plan
3)how much do you understand the business environment you will be operating
4)cost of settling down in the country (rent,feeding,transport......)
5)Don't forget the business will not be bringing profit the moment you start it
6)and other unforeseeable things (government policies)

Think about it very well before you make any move it maybe advisable to start the business in Nigeria (start small and think big)you can grow your business in Nigeria if you manage it well

Good luck
