If you are below 45 you can usually apply for skills migration instead of business migration which require you to plonk down a large sum of money.

Migration agencies can't "pull cable" for you but they can identify govt schemes where you can apply under to make it easier to qualify. My cousin paid RM10K for agency fees to apply to Australia and he got in under a little known Queensland engineering scheme.

Canada is your best bet as it is easier to get in. Forget about UAE. It is almost impossible.
