Bear in mind, that as in most of the countries, there are different requirements to start different kind of businesses. In most cases no special permit or license needed, nor the money deposit.
Several industries are regulated: financial services, medical treatments, export-import-wholesale-retailing of alcohol or petroleum, travel agencies, civil engineering and some others require extra permissions, or proof of proficiency, or proof of sufficient funds. Most probably you would not be interested in such businesses, but if you have doubts better tell what business you have in mind, and we can tell if it needs anything extra.
