Moderator's note:
Such vague questions from new members are often the precursors to spam from other new members (conveniently offering a solution). So this thread is being watched.
However, given that the poster is responding to replies on an entirely different thread, I'll assume that this question is genuine for the moment.
Even so, I find it difficult to offer any meaningful answer as it's unclear as where the poster lives ('corporate business' is a term more likely to be used in the USA than here in the UK) and exactly what it is he's seeking.
A corporation is simply a business venture entered into by a number of people (wishing to trade as a single legal entity), usually by means of forming a limited company (which divorces the finances of the individuals from those of the company, so that they can't be held personally liable if the company goes bust). In practice a single person (rather than a group of people) can create a limited company (although he'd need at least one other name on the paperwork).
So many small traders (such as plumbers, joiners, builders, etc) operate their businesses as limited companies, as do massive corporations (such as Amazon and Google). Thus, if the questioner lives in a major city there could be tens of thousands (or even hundreds of thousands) of such businesses in his area; I can't see how a list of them could be of much use to him though.
