Hello,
My name is Pavel, I can build you this project. The system will be a web app that will work as a web site and also open properly on all mobiles, today this is the best solution since you can benefit from SEO for marketing purposes. The web app will be 100% original in PHP (or Java, if you want to have enterprise-level system) with MySQL database and will feature custom CMS, no WordPress, no stolen or third-party scripts. Frontend will be made with Bootstrap4/MDBootstrap/JavaScript/AJAX, this is the cutting-edge UI technology. The site will be fully responsive and look well on all screens, including mobiles. I will also help you to install and setup everything, ongoing support for your project is also possible.
If you are interested, please let me know and I will send you full feature list for the system and write you detailed technical plan.
Generally, I build many projects as an independent developer, they are all custom coded with original features and twists. I have also won the grand prize in the Freelancer.com Developers Contest.
Thank you. Looking forward to working with you on this project. Available to start right away.
