Stdio64,
I hope it helps. People try to treat companies like they are people. usually, the company has bought photos before, so they will tell you if you ask. It is not personal, most will tell you their budget.
early on I had one that went like this.
them: How much for the stock photo?
me : ( thinking hard) it depends on the usage.
them: onetime usage..... we usually pay $500 per photo.
Me : I said that is fair. $500
I looked the pricing up, the range was $400-600 average $ 500!
Ask them. their answer will tell you alot.
