How about some realistic expectations. It's a well known fact or at least was when I went into flight school that your first few jobs would be crap pay, and you would have to sacrifice for a few years before you got the pay off of an airline job that would make it all worth while.
Brain surgeons don't get to skip internship because they have some cash laying around, lawyers don't make partner in a firm by throwing cash at the other partners, Christ, even a backhoe operator doesn't pay his boss for a promotion from dirt shoveler to get his position, they are all earned by hard work and dedication.
What kind of person would denigrate his chosen profession by paying to skip steps to get ahead, and ultimately laying the ground work for his future managers to degrade his conditions of service. When I take a management position 15 years from now and I see from your cv that you payed to fly, I will offer you half the salary I'm paying others, and you will take it because if you don't there will 100 behind you that are now willing to pay to fly as captains for free for 6 months or a year just to get a leg up on the competition.
