FTR - Freelance at whatever a person could be involved in seems to be the best route to take. You make your own hours, you make your own rules, you just need to be motivated and clever.He could go the freelancer route. Many sites to apply for jobs, but Upwork is probably a good place to start. However, don't expect instant results, it takes time. Personal question, but does he have any qualifications or experience in any fields?
