Have him apply to the fully-funded airline schemes which are likely to re-open in the next six months, if he's successful, you won't have to pay for his training and he'll have a very strong chance of a job at the end.
I'd be cautious about going down the whitetail integrated path at this moment in time anyway. The wider economic picture is not looking particularly great and if there are no jobs in 18 months' time for those who aren't airline-sponsored, having "trainee pilot" and little else on his CV won't help much in the wider job market. The best time to go down the whitetail integrated route is at the start of an economic growth cycle, otherwise I'd say to do the modular route around a part-time or even full-time job.
