PHP MySQL site with API integration for bills payment system

Greetings, I have a bills payments system (just like bayad center) this is hosted by ECPAY my service provider. I have their API Tech details and would like to create this on my own server to rebrand it as my own, I want to copy exactly the existing website plus make modifications to it. i will be adding additional features which the current system does not have just like adding balance for different branches and creating transaction limits. basically i will be giving you my admin password to view feel the actual site i want to copy to my server. I won't list down the features included in this project, just refer to the actual site and attachments i uploaded, it should be the same plus additional features that i will need. FEATURES: 1. There should also be and export options for the total amount paid with complete details 2. There should be a print options for complete details and amount paid 3. The custom bills payment balance and transactions should have its own transactions search, total amount paid and total amount of fees 4. There should be a balance setup per branch so that they will not be able to transact once their balance is depleted. 5. I want balance email notification once the balance is already low in funds for admin and users 6. There should be a balance inquiry with total amount of our commissions for admin. 7. For the custom payment system, i want to be able to upload a logo, create fees EX: Php 5 pesos per transaction, with configureable fields: required or not Account Name: Account Number: Reference Number: (optional) Total amount to be paid: I sent you an image of what i want it to look like:)
