Well if he has a PPL and 125hrs then he is getting close to the entry requirements for a Frozen ATPL course.
Now I may be talking out of the proverbial here but as far as I know, the study route for CPL is very very close to F/ATPL. In fact I am not so sure that with the good old JAA there is only one set of exams and they are the F/ATPLs.
Suggest that he finds himself a decent school and starts the theory side. Personally I am almost finished my theoretical stuff and found it difficult buy not impossible. If you read Pilot magazine you'll see that Jeppesen and OATS are getting together to publish the course work. Dunno on costs etc but the OATS books are good.
If he can hack that then find a decent school and do the flying. Once that is done he will have the CPL (F/ATPL) that he needs.
In terms of getting a job he really needs to look at not only a CPL but also the IR and Multi courses. If all he can do is single VFR then I suspect that he will be limited to para-dropping. Although that said I do recall seeing an advert for a salesman at Europa aircraft where part of teh job was flying aircraft to demo's. All that was needed was a PPL.
According to JAA Air Law; a CPL entitles the holder to act as PIC of an aircraft NOT engaged in commercial air transport (so air taxi is OK) or as co-pilot on an aircraft that IS engaged in air transport. Maybe he can find a co-pilot job on a corporate aircraft or the like.
All that said I would say that he will be up against a fair number of F/ATPL graduates who are all chasing jobs! In the hiring stakes I think that a F/ATPL beats a CPL if all else is equal (personality, hours, etc)
Good luck.
