Dumb Question (but I Need Help) [Edited: More Details and Pictures]

So, uh...is anyone here really good at identifying trees? Like, super good? Like, you can look at a picture of a tree (or maybe several pictures), check out its bark, leaves, flowers, and overall size and shape, and go "Ah, yes, this is [specific subspecies] of [species], more commonly referred to as [familiar name]?"

Because I have a few pictures of a tree in my neighborhood that grows white flowers, and I think the pictures came out pretty well. I'd like to upload them as potential stock photos for sale but I don't want to do that until I can find out for sure what kind of tree this is so I can label it accordingly, and I have been looking for two days and every time I find a tree that's ALMOST just right I realize it's the wrong size or the flowers are different or the bark is all wrong and that one detail is like "so nope it's NOT that kind of tree" and then I just have to keep looking AND I HAVE PUT A FEW HOURS INTO THIS ALREADY OKAY I AM TIRED OF LOOKING AT TREES

Seriously, help would be so much appreciated. I can PM you pictures if you want.

EDIT: I've decided to add a little bit more information. As far as I can tell it's a crabapple tree? I've got it possibly narrowed down to two kinds: the snowdrift crabapple or the spring snow crabapple. I'm leaning more toward spring snow because the flowers look EXACTLY right and the spring snow crabapple is sterile:



BUT. The spread of the tree is all wrong for that. A spring snow crabapple is oval and the branches grow upwards like so:



Whereas, well, here's a picture of the trees in my neighborhood--about as wide as they are tall:



So...I'm kind of at a loss here. =/ Help?
