About Exchanging Rates

I want to share about exchanging rate. Recently I started a business that requires us to spent at most AU$ 1750. In our rate it's quite amount of rate, it's equal to 5 months salary for someone who has a good job in white collar's level. But the amazing things is that this business is really booming in my place. I don't know what's going on but it seems that everybody here want to make a better life. And this business has proven that could change our life in quite instant compare to any other business. The corelations with the exchange rate is I believe that in some other place maybe AU$ 1750 is just small amount of money. If AU$ 1750 could make at least AU$ 3000 in about 1,5 months would it be a worth thing to take? Please do share with me your opinion. It would be useful to make a consideration to develop our business.
