Saburo,
Today I paid $370 for an airshow pic from a stock house. It wasn't my idea, and the design is ridiculous, but it's what the client wanted. An air-show team and a blurb about "teamwork" for the HR department of some company. It's soooo silly.

I'll post it here when it's done.
The point is...
The $370 was *cheap*. Prolly the least I've paid for a stock shot.
Your pics are of better quality (than this particular one and many others. But they have alotta decent stuff.).
The stock houses take a cut, but you get royalties... You might think of submitting your pics to some of these.
Getty images, comstock, etc.
Just an idea.
