Hello! I'm thinking about opening my own business. Is it difficult and expensive to organize an office space?

It depends on the building that you want to buy or rent and how much space it would have. Some money will go on rebuilding the interior too. You know, I think that you need to ask about its interior designers from referral links removed They've been doing the job for a while and know how to help you. Be sure to contact them and they will help you with organizing the space.
