You cannot 'receive remuneration' for any flying 'work' with a PPL. Absolute minimum is a CPL, but I gather that finding CPL written exams (i.e. not doing the full ATPL) is like the proverbial needle in one's haystack.
It is possible to drop parachutists with only a PPL but you cannot be paid for it. Best you can hope for is free hour building - but then everyone wants that so competition will be fierce.
Good luck.
