Three week holiday

Hi all my wife and I are both 50 and thinking of moving to Cambodia and we are coming on holiday for 3 weeks to look at the country and see where we want to live.  We going to go to siem reap pp and somewhere on the coast. We our thinking about starting a small business say a coffee shop or b and b we don't have loads of money so could you tell us what to look out for and the does and do nots
Thanks

Good luck but ya need to ask very pointed questions and I am sure many will help. I know a few expats here who own business and cold let you know the good and bad - but again pointed questions would help.
