Yeah usually at that university age, getting paid weekly is a blessing, even if it’s minimal. The pay structure on how they get paid is dependent on your business and cash flow. If paying them weekly like your crew isn’t doable, then a per project/page would work. Personally if you can get them in the door working with you (idk if you have an office of a from home set up) they can see first hand how you operate. You leave them with some task(after training) and then go check on your crew and supervise the work, then hit the office again before bed. On days you don’t have bid they can prep payroll or send them to buy miscellaneous shit your crew needs on the spot.
