Custom Prebuilt Admin Dashboard for eCommerce and Service Company -- 3

We are looking for someone who already have a custom admin dashboard for PHP, Magento, .NET, Python or any other languages they built previously for the customers similar to our needs. I have attached a layout of the .net estimation server we send to interact with customers. Customers can pick and choose their restoration, choose their dates and schedule times. The backend is massive, we want to downsize some of the details but start from new on a admin dashboard that is up to date and has room for growth. Please send some screenshots or video of your custom admin dashboard, so we get an idea.
