I have personal experience with this question. If you want to set up
interior design companies, and if this is your line of work and you choose to pursue it with a business venture of your own, please remember that opening a retail or brick and mortar will be difficult to do anywhere - only people that have been in business for a long time, and with a lot of money, ie. rich housewives etc. You need to get used to the idea that most of your business will come through word of mouth, networking. Understand this concept and know it. Any other way and you would have to make a large investment with no guarantees of what kind of cash flow you will receive.
