Well I took a look at your website.. seems pretty good.
I noticed you said you have 5 years of experience.. umm one question though.. do you have any sort of certificate? ie. A+ ?\
You might want to spot spamming your website, offer your services on the forum and not have them going else where.... pls.... you could be banned! or given infrictions and i have had 2 already!!
But, if it's any consolation..I didn't start till after high school and college.
Make sure you finish your schooling man..I know it sucks but we've all been there--save up some flow--wash dishes, get a paper route, etc..
Maybe start by offering a PC repair service--alot of our customers are also just 'drop-ins' that need a reformat, or replacement of this or that.
Make some flyers and do e-advertising showcasing your skills at repairing and troubleshooting. More people have problems with existing machines--than those who want to build new machine.
What I'm saying is--make sure you cover all aspects. You won't survive only offering one service.
