Starting a business in a foreign country will always be challenging. I don't think that the current state of the economy is what will determine if your business will succeed in the long term or not. Actually at this time it might be a bit easier for you to get a better deal for your shop (to rent or buy) ... although securing a loan from a bank is actually harder now.
