Hii....Im currently doing wedding survey as per below.....any idea where can I get the information?

1) The wedding market in Malaysia (maybe some comparison from the 1990's and 2000's), Is many foreigners coming here to organize wedding ceremony? Normally which area.
2) The growth of Wedding industry (Selangor/KL) which include overall expenses ( Hotel and restaurant Banquet, Bridal house, bridal photo-shooting, Wedding planner service for the latest this 3 years)
3) Understand from the web and there are at least 3-4 bridal fairs in KL. Any positive results or special request or demand newly?
4) What is the trend for the newly wedding couple looking previous and now?


Thanks!
