How to start a small IT business?

Hello team,

I want to ask all those who are experienced in how to start a small IT business.

What exactly is needed to start a small IT business and how to maintain it or carry it out efficiently. Where I’m from – not many IT business on the island and there are some IT consultant who does IT for people like, building websites, repair laptops, pc, etc.

I have a background in IT and I thought I want to expand it my developing a small business targeting repairs, service and maintenance of pc and laptops, building websites.

Can somebody help me out here. Is there any relevant resources, or important sources that I could use or relate to?

Many thanks team,

Timbo
