Build a Website

I am looking to have a simple paid sms chat website created. The end user would purchase credit that would be used to chat with the adult chat model. It would need to have a front end user website that has a payment method on it as well as a back end site where the model could log in, sign on to chat and manage how much to charge, conversation tracking, etc. If you need an idea of what this would look like look up arousr. If you have any questions, feel free to ask. I am looking to get this done rather quickly.
