How much is reasonable for a high schooler to charge to dust & optimize a customer's desktop computer for them? GeekSquad charges $149.99 to Optimize & Clean someone's computer, which I feel it's way too much. Or $129.99 for Optimization, but no dusting. Ray's Mobile charges $75 (+$25 additional PC) for just dusting. And $50-$75 for Optimization (Depends on drop-off or on-site). Considering these prices, how's much do you think I could charger for a similar service? ALL answers are much appreciated! Thanks!! -High school student living in fairly small town
