The content is top notch, no doubt. Unfortunately, you'd have to be in the .10-.20/image range for me to take everything. That's just the value that I assess to photos, no matter how good. I've already got 100k images so evidently quite a few content sellers see things the way I do.
If you hold on to your content too tight, you're missing out on money. Don't look at the discount as money lost, look at what's left over as money you NEVER would have gotten.
As an exercise, put things in perspective. You're saying that you want $3500 for all 75 photosets. Your stuff is nice and niche but the reality is that the nicest stuff out there generally goes for .50 or less. Just ask yourself what $1500 or $2000 would do for you if that was what you got for a sale. Quit being the artist that is holding on to his precious wares, become the wheeler-dealer that says 'HEY! If I get $1500 from Brad I can do another 15 photo shoots!!'
Ultimately, the sets as a whole are worth what you can get for them. There will be people that place different values on the whole collection. Personally, I know lots of companies like me that buy everything at once for half or more off. The problem that I have here is your content is two times what I value it at to begin with so half off is like paying retail in my mind. lol
Again, just my
...Don't misunderstand me, it's hott stuff! Those creamy white girls of yours are totally spankable.
