Need a PHP expert to work on a Wordpress project

Hello, As the title says the job involves working on a woocommerce site to develop a custom way of taking products. The timeline of for the project is 4 days at max and payment will be done once I see the work. (you can host it on your own hosting or however you want), you can hand over the code after the payment that is not an issue. You'll also need to work on a few more systems like notification and comments section. + make a custom page for vendors. The budget for this is $300. Please start with "I am a PHP expert" so that I know you have read this through. I can explain everything a lot more in detail over voice call or google meet .
