I find it difficult that you have only 86 P1 hours yet have 280 total. Have you logged the P1CUS where possible when training? You can count this is P1 time too.
Have a good read through LASORS 08 on CAA website, free to download. See where you can get those extra P1 hours.
As for working for free? Don't even go there on this forum. Been done to death and people won't thank you for it.
Good luck.
