hi - not exactly sure where to post this, but i'm designing another form for our organic lawn care business and need to find some lawn core aeration images (maybe the description of the plug coming out, side view of what happens when aerating, etc) and need them to be 300 dpi. so the images that i pull up under google are too small, so i need to purchases images from a stock photo site but cannot find what i'm looking for. anyone know of where i can find these? i've tried shutterstock, photostock, istockphoto, getty images, fotolia, etc....i'm getting frustrated..thanks!!!!
