Hi, @christian-horstmann,
I understand your frustration! There’s a definite need for more photographers that seek to uphold Godly standards in their art! Lightstock.com can be a good tool, though there’s still quite a few photos to weed through like other stock sites. I have a portfolio on there that you can take a look at, if you’re interested, with some photos in the categories you’re after – https://www.lightstock.com/users/creative-clicks-photography Hope that helps!
