Finish opencart 3.0 website

I am looking for someone to help me finish my opencart 3.0 website! I am somewhat familiar with the opencart 3.0 functionalities, but I need help adding and configuring extensions. I don't have any specific extensions in mind that I want to add and configure, so I'm looking for recommendations from the developer about which ones are best for my website. The developer would also need to do customizations of the theme and layout, and fix any bugs and errors. Thanks for considering my project!
