update website design

we are looking for a website developer who can change the website. The new design features have to be a modern, clean layout that is easy to navigate and visually appealing. Also, in responsive design for mobile devices, a search function has to be added to assist visitors in finding the information or content they are seeking, and improved navigation to make it easier to access different pages on the website. We want the new updated design to enhance the user experience and help visitors find what they need more quickly and easily. Online classes will be added to the website so the students will be easily able to connect to the class.
