selling pc, parts and repairing them but i dont really think anyone needs old parts like this and i dont know how to go about starting a business,
I have done custom builds since I was 13 (Got A+ cert then btw) starting with family,etc and I have now moved on to more customers and some serious pro level hardware (ie 2P systems). I don't do repairs or deal with any individual hardware sales (ie. I don't sell single HDDs). I only sell systems. I only build it once I get the order and they have paid for the parts. I charge $60-100 for a basic build with OS install,AV install,etc. I charge extra for OCing and water cooling. I ONLY provide warranty for hardware failure. I do not offer any software help,etc unless it has something to do with the hardware (ie. upgrading firmware). A don't charge people for simple upgrades (ie RAM upgrades) for the life of the system. However, I do charge if they want an upgrade like water cooling,etc.
And I don't sell to stupid people. Seriously. I WILL NOT sell PCs to completely clueless people. The headache with dealing with this type of people are not worth my time and I don't want these people to call me 24/7. My customers are either Sys Admins, DBAs, engineers, photo/vid editors,etc; basically people who know PCs pretty well but don't have the time to mess with OCing, keeping track of the latest tech,etc.
I NEVER run cheap cr@p on my customers builds. Period. If they insist on some cr@ppy PSU,etc I do not consider them to be a customer and basically tell them to GTFO.Hence why I have over 100+ system builds done and I have yet to have a system fail due to hardware issue.
I do not advertise. I get customers by word of mouth (and many will tell you this is the best kind of advertising) and I do not ship systems out of state .
This is how I run my business. Since I do make a decent profit per year I do get taxed
This is NOT meant as a primary money making way. I do this as a side job/business and I make a decent amount every year to pay for my PC upgrades,etc. But since I'm in college now I do have to start paying my loans (less interest that way). I can pay about 2/3 of the loans by what I make every year. Also realize that I live in a pretty well off area and isn't/wasn't really affected by the recession and there are a lot of IT jobs in this area. I did get hit a bit, but not much.
