EHH, I wouldn't count on that! I appreciate the Summoning, but I'm afraid I'm still too much of a novice in the hobby, and I won't lie about that! I may have gotten a strong start into my hobbies (reptile keeping and horticulture, mainly. inverts of course, but not nearly as well as the other two) due to my too many years of research and talking to people, but I have a lot more to learn and I wouldn't say I know too much. Sorry!! But I won't make things up or exaggerate my experience/knowledge. c:>
Still, reading this, regarding toads specifically I'm not sure, but frogs in general I have one suggestion. Josh's Frogs has been fantastic to work with so far. I haven't bought animals yet, but I hear good things about them, and they've been around long enough to make a name for themselves. I also like that they are at least really serious about how they ship their plants and inverts, and I've only had one plant get injured in shipping out of the Too Many times I've ordered. For amphibians, they mainly sell dart frogs, but recently they implemented their "certified breeder program" and are offering a few more new species, including hourglass tree frogs and pac man frogs. If you're looking to get more of those, this might be a good place to try. They also have a few other cool non-dendrobatid species...I'm partial to the solomon island leaf frogs (if they didn't bark like a small dog, that is!), borneo eared frogs, and the mossy frogs. Vietnamese mossy frogs especially are very handsome in person, and their call is pretty cute.
Maybe not quite what you're looking for, but it's worth a shot! Otherwise I'd suggest hitting up dendroboard, but it sounds like you've already asked on other places.
I will probably find them at a reptile expo.
