Build me a website and integrate an API to automatize my orders with my providers.

I need a website ( dashboard ), where you have to log in ( create an account ) to have access the dashboard. Once its created, you will have the products, and a global view of your active products. You will be able to generate your services --> This will do the action on my providers side by the API. And at the end you will get the product ( online services ) on your dashboard.
