Also, is there any way we can make our reputation good and be trusted by consumers?
Because definitely in starting this business there needs to be consumer trust in us.
Actually I want to support your business, but when I read this sentence it looks like you have a plan to scam after you've gain trust by customers. So I wouldn't tell you anything about trust and reputation in this forum.
If your business has a site and it's not only for exchange, you can create your thread on Service announcement board [1] If you're only offer currency exchange, you need to post it on Currency exchange board [2].
