so ive not built any yet but i kno alot about the parts and the operating systems in computers and i am going to take a class on computer parts. so would it be a bad idea after awhile if i got some experience and then started a thing where somebody would tell me what they want and i would charge them $ of parts + a 100 dollar fee + a little more if its a big job. would this seem like a good plan to u? and any comments or suggestions would b greatly accepted.
