For online exchange business, the first step is to find a reputable foreign currency exchange service provider online. There are a number of major banks as well as independent exchange providers that provide this service. In terms of currency exchange, major banks should always be considered trustworthy.
Independent exchange companies require a little bit of investigation. Exchange rates are constantly changing throughout the day. "Booking" an exchange rate involves registering an account, calling a representative or entering your transaction details online.

Many exchange providers will offer a quote to potential customers free of charge, which allows you to compare prices at other companies. The price they give you is the "booked" exchange rate.
Do not be surprised if the rate you are offered is higher than what is listed on trading sites. The amount of money being exchanged affects the rate of conversion so businesses trading in higher volumes tend to have lower rates than individuals.
Once you are satisfied with the quote provided, the next step is to send your funds to be exchanged. Many providers are prepared to accept standard e-transfers or bank wire transfers. Typically booked exchange rates apply to the say on which they were ordered. That should give you at least a few hours to compare prices before finalizing the deal by sending your money.
