<prompt> Human: So Ive had the idea to start an at home businessjobhobby where I basically get paid to build computers for people.help them pick out the parts in their price range they buy the parts then I can put them together for them or teach them howI have about 500 to start with and I want to know how I could properly invest this to get a good return from this idea. I am knowledgeable in this and can build a pc properly so thats not an issue.What stepsprecautions should I take when doing this? How can I get my name out there? How can I grow?Edit: it assigned the flair itself, Im on mobile and have no clue how to remove it  <response>: consider repairing tablets and smartphones instead. Computers are purchased much less often as people opt for laptops, which are rarely custom-built these days.
