Hello, I am looking for a person who could make a landing page + 2 tabs for me. The main page would have 4 product variants in different configurations and a simple offer proposal calculator. The customer, after selecting the configuration, would have to enter their information and then make a payment. Payment would have to be in a subscription or "upfront" model. I would like the process of sending invoices to take place automatically along with the subscription as well as the process of sending emails.
