There is plenty of market share for your service that you shouldn t fear the competition... you should make it so that they fear you. There s no reason not to start out the business part-time to see how lucrative it is. You don t need a shop ... you can work from home. You will get some awesome tax credits for your own business. You can write off alot of your expenses too. You also won t need a ton of money but should budget some for advertising to get the word out. Check out vistaprint.com for some inexpensive postcards. Try getting some business from local small businesses that won t have a staff IT person and also make yourself accessible to their employees for home computers as well. Write some articles on PC topics and sign off the bottom with your contact information. Consider a website and market the heck out of it. Have faith and confidence in yourself. With your own business you will earn 100% of the profits after taxes and expenses are paid. Can you think of any employer that will pay you that? You ll have freedom. But, again, start small and think big!!!
The best tip I can give you is to specialize in one area of the computer repair business and differentiate yourself from the competitors.While it helps to be a multi-skilled PC tech, you save energy and run an optimized business if you focus on a few important areas.I myself am in the PC repair business but my main focus is repairing LCD monitors plasma TV s. I also repair gaming consoles but LCD tech has been my bread-and-butter for the past 4 years.
