I need API Developer (Only Europe Expert)

We are creating a Cryptocurrency OTC service for mainly clients which use Wechat/Alipay to pay for goods. This will all be web based using the Wordpress platform. 1. Client with Wechat/Alipay accounts (Chinese e-wallet) scans the QR code(front end) to pay for goods using payment gateway API, to pay in CNY. 2. The client specifies the Cryptocurrency to buy, and their wallet address they want the cypto to be sent to. 3. The calculated amount of CNY gets converted to AUD + fees accordingly to the payment gateway's displayed exchange rate. 4. When the Payment is done, the program needs to send a trigger signal to the cryptocurrency's exchange using their API to buy the particular cyrptocurrency the client has specified simultaneously. 5. The cryptocurrency is bought, which gets deposited into the wallet address on the exchange. The program then withdraws the specified Cryptocurrency and is sent to the customer's specified wallet. 6. Email receipt is sent to the client to confirm transaction has been completed. Please answer the initial question with 88.
