I've got LOT's of ideas for businesses here. Send me US $2,000 for my full catalogue!!
Seriously though, don't even THINK of setting up a business until you have lived & worked here for a year or two. You need to find the way things work in this country (totally different to USA, Europe & Eastern Countries) & there are far too many people ready to tell you what you WANT to hear rather than what you OUGHT tp hear. As suggested above, read the archives, come & investigate & then find out who you can trust to do business with.This process should take you at least 6-9 months, then you have another 2 years trying to get the licenses etc needed!!
Good LUCK!!! - Grahame.
