is this something like arbitrage you want someone to partner with you and hows the deal will work? you want the funds to be escrow over?
its really a ig opportunity if what you offer will escalate properly but i doubt you will get someone to partner with you though.
This is an arbitrage on the market price of btc on different countries, but this will not happen because there is no collateral or guarantee that after OP sell the btc, he will give back the money with profit.
I suggest for OP, if you are making like that, have your family or friend personally go to that country where you can buy cheap bitcoins, and then do you business like that. It's easy money for you.
It happened here when The Korean btc bubble occur. Someone from Korea is buying too many btc here, and selling it back with the help if his family there, and he made around 20 btc at the time. That time, global rate of btc is aroung 2850$, but in Korea it goes around 4500$.
