I would recommend honing in on some specific cities within PHX that you'd like to target, as the metropolitan PHX area is very large. 

From that point, some sort of banking engine would need to be involved that was sophisticated enough to handle and understand trivial to highly complicated financial transactions.In any case, it would be fascinating to a small niche of people (myself included) so not too likely to become a commercial success.
