PHP/MySQL Braintree/PayPal implementation

We are an indie game who already has an outdated PayPal integration using custom IPN scripts; we would like to update our coding and also start to accept credit/debit cards on the checkout page alongside PayPal.

We also hope to add a couple of back-end tools for our game admins so that they can check up on PayPal transactions through the website rather than waiting for us to check in PayPal.

The project will entail:

• The purchase and fulfilment of our game’s premium currency that can be purchased in different amounts.
• Store records of the purchases in our database to allow users to view their transaction history.
• Automatically temporarily suspend player accounts if chargebacks/disputes are created.
• Admin enabling of special offers with the ability to either toggle the offers on/off, or set specified dates to be enabled.
• Admin search for transaction status either via the API or our own stored records.

We would need this developed using PHP 7 and MySQL (MariaDB), and would request that it is developed for us to integrate ourselves. We are looking for brand new code rather than update to existing, new table structure for storing transaction details, and we are willing to handle the front end implementation as long as basics are provided (any form fields/UI for taking payment, transaction details printed on a blank page, etc).

We have an existing PayPal developer account, and we have the existing scripts and database structure for the purchase/completion that we can forward for the project to show how we have it working at the moment.

We can be flexible on time scale, the sooner the better but we are in no rush.
