My recommendation is: create individual pages for those states and don't duplicate your homepage, as search engines frown at such practice. You stand losing the ranking of your homepage, if you duplicate its content. Make sure you add every targeted state in the Meta keywords and Meta descriptions of it's personalized page. E.g.: newyork.php will have personalized Meta descriptions as "New York financial investment company". So, when someone searches for "New York investment company", newyork.php will be served by the search engine. Use keyword variations that are similar, but not exactly the same.
