You are right about the condition of the country, so in mine I think it will definitely be the repair of the pc. Although
@Alexandoy mentioned the opportunity to sell pc on consignment. Which is possible in case someone wants to buy one.
It is very important what you describe
@Oliver4smile , when the person in charge of repairing the PC is professional, very soon potential customers will come to the business looking for their service
Of course it is better to buy a new PC, however the economic situation often does not allow it, and that is when the repair business will pay off.
