i want Build an Website

Please mention 'R1" starting with your proposal I have Created Website In 'WIX' Now i want to change in Php I need some features and organization to be added. We need the site to be smooth both desktop and mobile without changing the overall design. Some optimization and scaling is needed. Also we want to offer some features like: - limited registration for our training courses that we are offereing in sequence. This would allow us to let a limited number if unique individuals (40 for example) to register for the course at a time. They would have to click on a link to take them to our payment page. They would pay a registration fee and then before they enter the course and in order to get the link to the course (conducted on Microsoft Teams) they would need to pay the remainder amount. This needs to be linked to a database for future record and tracking. Also we need the current forms on our website to have automated replies that we did not setup yet and also a organized database for each contact form and so on. Also want to Add 1 extra page for E-commerec Total pages - 13 pages informatic ( i need access in back end to change content ) - 1 Page E-commerce - 3 page service page in that different types of service can be selected ( service is about product development consultation , Training ) - There is Regiseration process and package section option available in package there is seat selection admin can restrict number of seat allocation if that number of seat allocated , Registration has been closed automatically - Website has 2 language ( English & Arabic ) There are certain pages on the site that have problems more than others like the Consulting pages for example. The links at the top don’t get you exactly where you need to be at all time and on all platforms
