My suggestion is to do the right job at no additional cost. It’s an incredible waste of your time and resources (also I know nothing about the time or effort it would take so full disclosure, I am talking out of my ass) but you would walk away from the job feeling good about your work. Perhaps the owner would appreciate your efforts in some meaningful (monitory) way. Perhaps they would simply speak highly of your work ethic and other people would hire you and you could raise your rates to make up for all of the work you then have. Perhaps also the price of crypto will go through the moon and your mining rig and posts on Steam will make you rich!
