I believe during registration of individual entrepreneurship, one needs to declare types of economic activity. Is it allowed to have categories completely not related to each other? For example is it permitted to establish individual enterprise that would provide photographic services and sale home decorations on-line? Or two companies should be registered?

following.. as I would be also interested to know..

(my main focus would be in wine import and retail). Is there a list where potential activity categories can be checked? I only saw a free text field on the application form.. would be good to know if some activities definitely require an LLC, and can't be done as Sole Propriator
