Business Start Up

I am planning on starting a company next year. I already have a business plan; 2 year cash-flow projection etc.
I have 30 years in the industry I plan to trade in & market research has proved the product / service I intend to offer is not currently available in The Gambia.

What pitfalls should I be aware of ?

How difficult is it to start a business ?

How do I go about opening a business bank account etc ?

Any advice will be greatly appreciated
