Thank you, bitmarket.net

You have really understood my concerns and highlighted relevant areas;

For the most part I will taking fiat currency from customers (dollars/pounds) and converting these to bitcoin.
I will buy/sell bitcoin in the destination countries.
I will buy/sell bitcoin in the originating countries.
Keeping currencies within local countries and their banks should limit bank transfer fees. (am hoping).
I intend to only move money from exchange to my local bank account, and move from my account to clients.

Yes; you've highlighted a main challenge, how to move money (fiat) in and out of exchanges. I guessing Coinbase and Kraken are no, no.....
Am thinking Far East based exchanges maybe better for my purpose, any thoughts or suggestions?

thank you
