First you might want to break up the domain up there, use () instead of . or something. NP gets indexed by Google pretty quickly and you don't want a potential buyer stumbling upon this thread.
Second, I'd say the difference between "aid" and "aide" in terms of meaning is significant. Financial aid means a loan or grant to attend a college, mostly. A financial aide would be some sort of tool you'd use to do your finances -- think TurboTax or something like that. Financial aid as a phrase is much more valuable.
Looks like all the extensions have been taken for a while and by different folks, so no intel that you can glean from that.
