None of them will be enough to sustain you. Computer repair people are dime a dozen. If your websites are not already bringing in revenue, they will not start magically doing it as soon as you lose your job. And there are already hundreds doing the website/programming thing already. Just search for webdesign
I took laptop of my kids which was under extended warranty plan to Best Buy , they ran a diagnostic and said it had trojan and it will cost me 130 dollars to get it removed since that kind of repair is not covered under the warranty plan, then for data backup they said it will cost me 99 dollars .
I told them hey buddy you just take care of the keyboard which aint working I will take care of the rest , they called me after two weeks to let me know that they have replaced the key board.
Many friends of mine know that I am in IT , I do all this for them for free and they are so obliged. But when I sit down at a community gathering I hear those horror stories where they ended up paying 100 dollars an hour to get some virus or trojan removed.
You are telling me that computer tech are dime a dozen , may be where you live , where I live they charge $100 dollars an hour for the things I do for free for people.
