Payment Gateway for Crypto

I am looking for a developer who is competent in PHP, SQL and JsonRPC to create a payment gateway for my site that can be enabled and disabled as per our other gateways.

Gateway must do the following

1. Generate wallet address for user to deposit from admin payment settings and adhere to min deposit rule

2. Accept the payment and take deposit fee set in admin through the gateway script and update that users balance in SQL database on successful deposit / alert on deposit not recieved.

3. Allow users to create withdrawal requests if enabled as per other gateways - withdrawal requests are sent to admin page (already exists) for admin authorization and must pay the user once approved.

Deposit balance is not taken directly from the crypto wallet but from sql balance so other parts of the site continue to take coins per user interactions on the site.

Admin approved withdrawals are taken directly from the crypto wallet (based on bitcoin source) and pay to the user submitted wallet address in withdraw form.

If unsure on anything message me for clarification, i will respond but does not mean i will award you unless the price is right and you understand what i want.

PHP script you will be working on is NOT opensource and is Licensed for my domain

Skills: PHP, MySQL, Software Architecture, SQL, HTML
