Improve the online store on YII 2

Hello.

It is required to improve the functionality of the online store (renting things). The site is written in PHP, the YII 2 framework.
It is necessary to screw the payment to the Paypal, DHL delivery tracking, introduce multilingualism and refine the order logic. I will send a more detailed TK personally.

You need to get the job done urgently, so if youre ready to start right now and do it quickly, then leave your contacts.
