My suggestion is : "Don't do it". Let me elaborate on that :
I am an IT professional for the last 14 years and since I work in this industry, Your friends and familly will become customer. they will no longer call you to have a beer or lunch without a idea behing their mind. Exemple : let's invite Joe for lunch, he can maybe look at our computer later. Excelling in computers is a curse.
If you go in webdesign, you friend and familly will ask you to build website for them for free of course. They will try to start on their own but soon you will be their major source of information. they won't use google or forum but your phone.
In a brighter note, there is solution. I setup a basic price for my familly and friends. If they call me for any technical assistance, they know i will charge them a minimal price, no matter what it is. It's to make sure they only call me because they really need help. I'm glad to assist them when they call because I know they will call serious issues and not simple "how-to" questions.
Working in computer could be a very fullfill job, Just remember this, One day you will the hero, the next you could be a zero. If you can learn to live with that reality, then this type of works is for you.
